Sometimes it takes one thing, to make another thing come into focus.
Twitter has been like this for me. I tried Twitter a long time ago, and just could not get into it. However, recently I posted about a great new IM system called Digsby, and Digsby has brought Twitter back into my daily routine with ease. As usual I have to search out a system and see what types of tools, updates, APIs & plugins are available. It’s just my tweaking nature.
I found 2 excellent resources for additional Twitter Tools, everything from standard API calls to WordPress Twitter Plugins. If you want to extend your Twitter, check out these pages for some great additions.
