Not necessarily something I need as a user, but something I see as valuable to folks looking to hire via Careers 2.0.
Similar to how tag summaries are shown when searched for during the tagging of a StackOverflow post, why not provide those same tooltips on hover?
Potential benefits I see include:
- Help recruiters / employers who might not be familiar with the technology.
- Gives candidates a leg-up who may have similar or complex experience in an unfamiliar technology by highlighting what the technology does.
- Encourage candidates to use more accurate and meaningful tags
- Encourage the expansion of the tag library with technologies that might not be discussed often on SO.
