Last month Google looked a over 1 billion pages and compiled statistics regarding the usage of HTML tags, attributes, classes and meta data. Quite an interesting read: Google Code: Web Authoring Statistics.

Mozilla is working on a developer site with Wiki based documentation for web development: http://developer.mozilla.org/en/docs/Main_Page

An excellent idea, it would be great to get (X)HTML, CSS, XML... reference documentations here. At some point I was thinking that Wikibooks could host such documentation, but Mozilla is a better place I guess, more focused. I hope it will take off.

Very neat idea, distribute the work of creating browser shots for different browsers and platform: Distributed Automatic Browser Screenshots. Not sure how will this project take off, if people only use resources and don't give back then it is not going to work. It seems quite hard for an average web developer to give back, complicated setup is needed.

One of the commercial sites I have seen is BrowserCam. While not too expensive for a commercial project, for open source projects it is almost a no go.
