I have 3 Twitter accounts.
What's the best solution for handling multiple Twitter accounts?
I've been using splitweet for some time, but it's buggy, and its support for retweets is limited.
Any good solution for multiple account tweeting?
Most modern clients should support multiple accounts. I can recommend Tweetdeck It supports multiple accounts.
There are evidently a lot of solutions, so I'll just add Brizzly to the mix here, which I have been quite fond of.
I manage four accounts through Tweetie without any issues, though pretty much any client will be able to do this for you.
Ah, I have been using HootSuite for a long time. It's a webapp so I have it everywhere. I use it to manage my Twitter and Facebook accounts. Some other social networks are also supported. I have never been disappointed.
Cotweet is designed to handle multiple accounts, and is a very slick web-app to boot. One of the best (designed) I've ever used.
Researching this today I also came across Multwiple which I have not tried, but this blog post is a more recent (Feb 2011) endorsement than the others mentioned here. I have not yet tried it as I'm not sure which one to choose yet and don't want to waste too much time trying them all. http://www.calvinshub.com/2011/02/managing-multiple-twitter-accounts-with-multwiple
