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 that limits the length of the comments you can post to 140 characters. So, it is unsuitable for posting large chunks of content, but ideal for posting links to other sites containing interesting information.
Twitter is highly interactive and users often re-post, as well as respond to, other peoples comments (tweets) if they are useful. You choose who you ‘follow’ (ie, whose tweets you read), so it is a great platform for making contacts and establishing relationships.
