I've been using Twitter for a while, and have amassed a few hundred people whose Tweets I follow. They're professional colleagues, friends, people who I know, and some relative strangers who say witty or insightful things -- the reasons I follow people on Twitter are varied. But one way or the other, they're all people with whom I share common interests or some kind of connection.

In the past day, I've lost count of the number of times I've seen this Tweet:

"I bought the @MacHeist 3 Bundle. 12 Top Mac apps worth $900+ for just $39 AND I just got Delicious Library 2 FREE!"

This is beyond irksome. It irritated me into a frothing rage last night, and I'll explain why in a moment. First some background:

MacHeist 3 bundles a collection of shareware together for a price far lower than you would pay for them separately. And this latest MacHeist bundle includes titles as varied as the eBay sales tool iSale, the physics game World of Goo, Ambrosia Software's audio app WireTap Studio and Cro-Mag Rally, the caveman racing game from Pangea Software, along with a number of other apps. What's more, MacHeist "unlocks" additional apps to be included as part of the bundle as more copies are sold (ostensibly, as their charity donation increases).
