Search by Tag is Live....

You can now search for RateItAll reviewers by their People Tags.

The next step will be a tag cloud, that will look something like this.

I think this is a pretty good tool for making sure your tags match what others are doing... for example, if I tag myself "hoops" but someone else tags themselves "bball," we're not going to match. It may be worth it to double check your tags in the search to get the most mileage out of this feature...
