I'm using Tweetdeck mostly to post, but find that I still revert to the Web version a lot.

tr.im your URLs is a neat url shortener.

Please share your recommendations here - new applications are created everyday!

I use:
Twitrobot for posting regularly, which I think is great. The free version gives you 10 options for tweets, they are sent out automatically every 3 hours, all I do is change a couple every day. The reason I use this is so I can get the message across to people all over the world... maximising readability and clicks on each link I add.

I tried using Splitweet, as I manage 5 different accounts, however it didnt show updates on all my accounts, only certain ones. This could have been a really good application had it manage my accounts better - showing ALL updates.

Now I log in and out of each account throughout the day - I find its much easier, and with Twitrobot the accounts are managed much easier anyway now

Does anyone have any tips on other applications i could try to manage several accounts?

After the twitter training i attended by Andy Atkins Kruger (WebCertain's MD) i decided to have a look into some of the APIs discussed and which he uses:
Topsy.com - tracks links you post on twitter (be great for using for clients)
Twhirl and TweetDeck - enable you to manage your twitter following
