Here’s an interesting one for BB users: if you’re looking to expand your media awareness on a certain topic, Twitter is one of the best modern hot spots for discussion. One of the cool things about it is that it’s pretty easily searchable, and you don’t even need a Twitter account to take advantage of all the information being tweeted around. Twitterlerts takes advantage of this by automatically searching for tweet topics you’d like to be alerted to. Just type in the key words and the app will ding you when a new tweet is found — from there you can view it or share it with friends or co-workers in a quick e-mail.

If you’re interested. Twitterlerts is available from Electric Pockets for $4.99, and there’s also a free trial on Blackberry App World.
