Okay, I've searched and I found almost nothing regarding what is so bad about MacKeeper. Only 3 things: Messes up Safari's ad blocking, slows Safari to a crawl, slows the system to a crawl. I've not had any of those problems. While Lion was taking forever to empty the trash (that is, it was stuck on the same number of items deleting for over 24 hours), leaving me with no system based way to empty the trash but to wait and hope it would eventually do the job, since I couldn't remove but a fraction of what was in the trash because I didn't have enough space on my hard drive, MacKeeper enabled me to delete the largest single item (a full back up of the user file), which took a couple of hours, and is now about 15% through the rest of it (121 inremental backups) after an hour and a half. Maybe MacKeeper's bad. I don't think it's the cause of the problem. I'm not using most of the features, anyway. At any rate, the search informed me of other options which I'll definitely look into, so thanks for mentioning it.
