Twitter has become increasing popular over the past year or so with everyone who’s anyone Tweeting their little hearts out. Twitter is a micro-blogging site which limits the length of the comments you can post to 140 characters. It’s no go for posting large chunks of content but ideal for posting links to interesting information.
Twitter is highly interactive and users re-post other peoples comments (Tweets) if they are useful and also respond. You choose who you ‘follow’, i.e.: whose Tweets you read, so it is a great platform for making contacts and establishing relationships.
