One thing that I failed to mention in my last post, which is an extremely useful feature of Twitter that has enabled me to find many of the people that I currently follow is the “Track” feature.

You can simply type “track X”, or “track X Y Z” and twitter will automatically send you anything that anyone says that includes that word or combination of words.

Politweets is a great, and recent example of this awesome feature in use. It tracks what people are saying about all of the presidential candidates, and presents the comments side by side in a nicely designed interface.

Steve O’Hear gives a great overview of this over at ZDNet, as does Josh Catone at Read/WriteWeb who also gives some other great examples of the power of the Twitter “Track” feature.

Just one more reason to start using Twitter!

Have you come across any other extremely useful Twitter mashups? I’d love to check them out.

I came across an awesome new app today called AideRSS

AideRSS allows you to easily track the amount of buzz/response your blog posts have generated.

They also have created a scoring system called PostRank™, which ranks blog posts based on relevance and reaction/buzz.

Rather than rehash a lot of what has already been said, here are some great detailed write ups:

Sunir Shah from Freshbooks.

Josh Catone from ReadWriteWeb

Pete Cashmore from Mashable

I’m hooked.
