Gnip, a company that provides technology to help other web services quickly share information provided by users, has raised $3.5 million.

Here’s how Gnip works: When a user updates their information on a site like Digg or Twitter, it takes that information and updates it quickly on the user’s accounts at other sites, such as Plaxo’s personal information aggregator service, Pulse.

The San Francisco, Calif. and Boulder, Colo.-based company has already signed partners like Yahoo and Plaxo.

The investors in this round include previous investors Foundry Group, First Round Capital and SoftTech VC; they previously put in $1.1 million.

In developer-related news, Gnip recently decided to stop supporting the XMPP protocol, which allows for “real-time” or near-instant information sharing between two sites. It’s one of several protocols that Gnip has supported. From ReadWriteWeb:

[Gnip chief executive Eric Marcoullier] says there are simply no open source Jabber servers that are capable of the kind of robustness that a social media ping server requires. If a major vendor came to Gnip and said they wanted data streamed to them exclusively in XMPP, the company would continue the practice, but the long tail of tiny consumers that want their data that way is taking up too much resources. The company’s top priorities are data delivery and maximizing the number of publishers participating in their program.

After another night of downtime there is some good news coming out of Twitter land this morning. The micro-messaging service will open up its XMPP data — known by some as the “firehose” because of the massive amount of service data is sent through it — to new startup Gnip, according to TechCrunch’s Mike Arrington.

This is big news not only in that it means Twitter is feeling confident enough about its service to give XMPP data to another client, but also because Gnip’s purpose is to serve as a middleman of sorts for between data sources and users. This basically means that anyone who wants Twitter’s XMPP data will have to get it through Gnip.

After we wrote about our disappointment that Twitter was not one of the services utilizing Gnip when it launched on July 1, founder Eric Marcoullier left us a comment saying that Gnip and Twitter had been talking since Gnip’s inception. He said as soon as Twitter worked out its XMPP data scaling, Gnip would hopefully work with the service. The time has arrived.

Up until now the only services that had access to Twitter’s XMPP data were Twittervision, Zappos, FriendFeed and Twitter’s own recently acquired Summize.

This data will only include status updates for the time-being, and not Twitter’s other useful data such as @ replies and direct messages, Arrington says. Still, this is a great step forward for the service to open this data up to such a potential large usage.

update: As Marcoullier just wrote on Twitter: “It’s official: Twitter is pushing to Gnip and Gnip is pushing it the f**k out to everyone!” Clearly he’s excited.

Update: The company says that Twitter has been working with Gnip. See comment, below.

Most web users will probably never hear of Gnip, but millions will start receiving the benefits, starting today. The San Francisco-based company’s software service acts as a middleman, making it faster for any two web services to share specific, publicly available data back and forth about individual users. The result is that web sites can much more quickly display recent information that pops up on other sites.

Large web services like Digg, Plaxo, Six Apart’s various properties, del.icio.us, Flickr and a range of startups are already launch partners, with more popular web services to come.

Here’s a more detailed example of the problem Gnip (pronounced: guh-nip) is going after: Plaxo, the online address book company recently bought by Comcast, introduced a new service last year called Pulse, that aggregates your activities from other sites around the web in a single, flowing stream (as Friendfeed, SocialThing and others also do). In order to discover which Plaxo users have, say, uploaded a photo on Flickr, shared a link on del.icio.us or dugg a story on Digg, Plaxo has to keep sending automated requests to these sites to ask for updates about each Plaxo user. Because only a fraction of Plaxo users have performed an action on any one of these sites at any given moment, Plaxo ends up asking for updates about many users who haven’t done any updates — a waste of time and effort for each site involved in sharing this information.

Plaxo lead engineer Joseph Smarr explains how Gnip is better for Pulse:

Pulse tells Gnip which users we want updates for (e.g. which Digg users have shared their public feed of dugg stories in Pulse), and whenever any of those users digg a new story, Gnip proactively notifies Plaxo, telling us which users have new activity, all within 60 seconds! Using Gnip, Plaxo no longer has to poll with high frequency to get quick updates–in fact, not only can we poll less frequently (which helps relieve the load on both Plaxo and the publishers we’re currently hammering), but we get updates much faster than we could before. It’s a classic example of a win-win created by reducing inefficiency in the system overall.

Gnip plans to flesh out ways for sharing data between various protocols, including REST, XMPP, ATOM and others. It is also working to ease integration of the XML markup language across services, making it easier for a given service to integrate with a new site that begins sharing data.

Note for privacy advocates: Gnip only shares user data that partner sites already make publicly available, so the company isn’t at this time exposing anything that users have already designated as private.

Zooming out, Gnip has put itself into the middle of a big trend. All of the companies I’ve mentioned here have spent at least the last year or so working on ways of sharing their own user data and absorbing data from other sites. So have many others, like social networks Facebook, MySpace and others.

The end result is that the average web user will start seeing things like friends’ updates from other sites much faster than they are now. Sadly, as Dave Winer points out, beloved but technically troubled messaging service Twitter is not currently a Gnip partner — meaning the many other services that access Twitter data won’t see Gnip-powered improvements.
