Never used in url to check if it's indexed before, but I do use site:"Web 2.0 URL". I'm sure other people have their own faster methods, but I do a GSA blast to index my Web 2.0s. On average it will take up to 2 weeks to get it indexed.
Looks Iike I haven't been paying attention. Thanks for clarifying. Now that I think about it, I did read something like that.Google has stopped supporting the site query.
You could also use a @seb_ali comments service to get the web 2.0 indexed.
Not that it is news, but Google is currently really slow to index any page at the moment.
