A friend of mine got a mac recently. He hasn’t used Mac OS in a very long time. He was asking me about applications that I use.
I told him about spirited away, Snapz Pro, Cyberduck, Bloglines Notifier, FCP Rescue, Mac the Ripper, Mediafork/handbrake, Monolingual, mpeg Streamclip, and Text Wrangler.
But I did not tell him about Quicksilver. I use quicksilver more than any application. It’s uses are really unlimited. Check out this link to 43folders for any post related to Quicksilver, this is where I heard about it (and learned how to use it).
