Twitter is the social network du jour and there is certainly no shortage of clients to choose from. Kiwi is a Mac Twitter client that prides itself on its level of customisation as well as its powerful set of features.
As well as supporting pre-made, as well as homemade themes, Kiwi's interface can also be personalised so you can see as much or as little information as you need. For Twitter dippers, a minimal interface is available, while those dealing with trending topics, saved searched and multiple accounts can choose precisely what should be visible.
Rules can be used to ensure that the content you are particularly interested in gets highlighted, and tweets you are unlikely to read are ignored. As well as handling single or multiple Twitter accounts, your contacts can be organised into groups so you can view tweets exactly as you want to.
In Kiwi you'll also find support for Twitters newer style of retweeting, inline TwitPic images and great performance. But it is the customisation of your personal timeline that makes this client stand out from the competition. This may not be a free client, but its features mean that it is well worth parting with a little cash.
