I like to share not only source code, also tools.
This are my favorite Twitter tools and since they are my favorites for me are the best.
TwitterFox – Great extension for Firefox, makes really easy to tweet and follow conversations.
Friend or Follow – You want to know who are you following and is not following you back? this is your web site then 😉
TwitRobot – In this site you can create scheduled tweets, campaigns or use you feed to automatically tweet every X time. Almost spam but useful
Qwitter: e-mails you when someone stops following you on Twitter with a message.
Twitter Badge generator – Generate a Twitter Badge for your site like the one in the right side.
Twitter Search and Follow – Search for terms with your twitter account and follow
Any other good one? I’m still a bit newbie in Twitter btw…
