I think you have valid concerns Daniel. But I would encourage you make generous use of the block and unfollow functionalities. There are plenty of people on Twitter vying for your attention, don't give those who abuse it any more of it.

Thanks for the article.

(About the MacHeist TweetBlast, I'm slightly ashamed to admit this, but I have a separate twitter account for posting such marketing material. This way I don't spam any of my friends who don't specifically want to see tweet blasts and other "social marketing" wizardry. Honestly, I don't think anyone wants to see that sort of stuff.)
