Thanks for your kind comments Kenny.

I actually like having a separate Twitter client so I can Command+Tab to it, and also ignore it without having to ignore my IM client. In this day and age when we have gigs of RAM I like to have one application per task and I don't care so much about using my RAM. I've bought it so I may as well use it :)

I've actually settled on Twhirl as my client of choice. Once you change the colour scheme it's a very nice client.
