Another area in TweetLater I’ve found to be very beneficial is the Keyword Alert digests. (http://www.tweetlater.com/alerts)
You’re given the option to type a list of keywords you’re interested in, and then select how often throughout the day this digest is sent to your inbox. You’re then mailed a list of tweets pertaining to those keywords. This is an invaluable tool, and certainly aides in finding relevant conversations to join in on. One of the greatest ways of producing connectivity and contacts through Twitter is helping others. Implement keywords related to your niche, or talents you’re proficient in – and give advice and input on others problems.
