I really like using Stack Overflow for problem solving in communities around open source libraries. One problem that I've found is that it seems to be difficult to guide users both to existing questions that may solve their problem and into asking properly tagged questions. While we can link "ask" with a pre-filled tag directly, there's no explicit call to action when viewing a tag's page.
I'd love to see a "Ask A foo Question" button displayed somewhere prominently when viewing foo. This means we could link to the tag page to encourage users to search for existing answers, but also provide an easy means of asking a question from this jump-off point. Is this something that can be added?
