Here’s my selection of tried and tested Twitter tools for December 2009; in no particular order:

1) Listorious - a fantastic site to discover Twitter list and a great tool to identify other Twitters of interest.

2) Brizzly is an aesthetically pleasing web-based Twitter client, which lets you manage multiple Twitter accounts / Facebook profiles, whilst also offering  a number of nifty ‘extras’ such as being able to view full URL (as opposed to bit.ly tiny URL links) and the definition of trending topics. I personally love the threaded DM feature.

3) Must Exist – a cool little site that lets you create a personal lists-based tag cloud

4) True Twit – a site that validates your followers for a spam-free Twitter experience!

5) Twitter stats – in their own words, a  service which help you to see Twitter stats based on your chosen keywords!

6) The Twitter Times – just like the Times newspaper but for Twitter

That’s all for 2009 folks! Have a fantastic time tonight and see you all in 2010!
