Here are some Twitter publishing and tracking tools that I’ve been using a lot recently…
TweetDeck – installs on your desktop and is a useful program from publishing and monitoring Twitter activity – www.tweetdeck.com
TweetStats – provides statistics about your Twitter activity, and if you put others’ names in you can get data about their activity – www.tweetstats.com
TwitGraph – more or less the same as above, not as nice an interface but you can save the graphs as JPGs to drop into reports – www.twitgraph.com
TwitterFall – initially quite confusing, this is useful for tracking activity on Twitter – www.twitterfall.com
TweetBurner – shortens and allows you to track use of your URLs – www.tweetburner.com
Trendrr – compare Twitter trend activity – www.trendrr.com
