I heard about TwitterJobSearch on net@night, and decided to give it a twirl. I typed “mysql” and found 3,092 results in 30 seconds. You can then filter by job title, salary, skill set, job type, and more, as well as sort it by relevance or date.
Useful? Quite possibly. Would be more useful, if you could filter out Twitter users (like @itcareer, for example). Search that is semantic, instead of just word based. So “mysql in san francisco” will return relevant results for you.
If you’re looking for a job anytime soon, note that there will also be a Job Fair at the MySQL Conference & Expo 2009, happening April 20-23 2009, are you registered yet? Its a great place to network, and you shouldn’t miss it.
