I'm in the technical field, so I like to go to different job boards to get an overview of where different positions are, as in how many posts there are for java, microsoft, php, that sort of thing, but also typical salaries for those positions. I realized it could be a lot easier, so I put together a mashup that will show many different positions across a wide range of job boards.

I thought it may be interesting to many of you here.

You can click on the different bars on the charts to drill in and see how the total job posts for that search term has changed over time.
