stickis.bmpStickis offers a service that lets you post notices — or stickis — on Web pages, viewable by people who have chosen to read your notices.

We first mentioned the San Francisco company in July, when it first got $600,000 in funding. It is about to close on a second round of angel funding.

It is useful for collaboration, and research. Let’s say you’re interested in getting the GigaOm take on a company, say, Riya — but are also interested in getting VentureBeat’s view, and perhaps even stooping so far as wanting Techcrunch‘s opinion. You don’t want to go to each of those blogs to search for the reviews. Instead, you can just go to the Riya homepage and see them all there, via Stickis’ service. In other words, you can take your favorite blogs with you. It’s good for group research projects, and collaboration within companies about views on sites of competing companies, for example.

Techcrunch reviewed the company here. Stickis has lots features best learned by playing with it. One of the main features is the “channel.” Any note I leave on a site also becomes part of my channel, so that someone who has subscribed to my channel can see anything I write, about any site. Similarly, if I subscribe to the channels of five people, I see a continuous stream of the stickis those five people are posting. I can keep these channels in view, or hide them. Moreover, sticki notes don’t have to be written on Web sites — users can write a note about anything, and it will be included in their channel (see screenshot below).

There’s much more here to noodle with. There’s extensive tagging. If you subscribe to Yelp or OpenTable for example, and then visit a restaurant Web site, you can see sticki reviews of the restaurants or make a reservation for it. Stickis wants to make money with these sorts services, though it’s unclear to us exactly how this particular avenue will scale.

Here’s a screenshot of a sticki on a Web site:
