Wanted to second this recommendation. I've been using Twitter Tools for about two+ years and it's always been great. An especially nice feature is that it will allow you to categorize your stream, allowing as I do, to archive your tweets without making them appear on your homepage. It also supports a digest mode (again, really useful for my application). - Matt ----------------------------- Matthew Bernius PhD Student | Cultural Anthropology | Cornell University | http://www.arts.cornell.edu/anthro/ Researcher At Large | Open Publishing Lab @ the Rochester Institute of Technology | http://opl.cias.rit.edu | @ritopl mBernius@gMail.com | http://www.waking-dream.com | @mattBernius
