Indeed. I just got a spam from Equinux on Wednesday (makers of iSale, from the MacHeist bundle this past spring). It did have an unsubscribe link, so we'll see if that works. But the email was certainly unsolicited and a nuisance. I've never used that particular application, and most likely never will. Like most in these bundles, it seems to be a shiny solution looking for a nonexistent problem to solve.
As for this bundle, I don't see anything worthwhile in it. Don't use twitter, don't play games on the computer, vi is my word processor

D), never understood screenshot apps when OS X does it perfectly, and my Desktop is my "Shovebox." I could download it because it's free, but just as with the many free songs offered by Amazon MP3, my time used to try it and manage it is not free.
For those who find it worthwhile, though, I'm happy for you. Hope you enjoy it.
