I am still running the last Adobe Air version of Tweetdeck (0.38.2).
No other program I have seen can match it's features I have tried a few programs and websites/services and can't replicate the following

  • Integrates multiple twitter accounts with Facebook
  • Allows you to sort by oldest first &/or
  • remembers what you have read and takes you back to the oldest unread

Programs/services I have tried include Tweetdeck (new), Hootsuite, bottlenose.com, and a few others too.
Janetter works in the way I like for Twitter - but doesn't do Facebook

Any suggestions for clients that might suit?
Happy to pay for something that works the way I want
What do you use?
