Not bad if they really are adding stuff weekly to PS+ members. Couple that with the fact that it's confirmed that all PS3 users will have access to Hulu+ (after the initial PS+ preview period) and it's been a decent launch for the service.
EDIT: After doing the math I bit the bullet and signed up for PS+. Now that it seems like we'll get content and offers more often than once a month, it is something I think will pay for itself. I'm not even all that interested in some of the popular features like auto-patching, but it's nice to have I suppose. For me it comes down to cost savings more than anything, and perhaps a few cool betas.
It costs $3.33 a month, and by signing up I instantly saved on purchases I was going to make regardless. I'm already ahead of this month's savings quota: the Hamsterball discount, the free MahJong DLC and the Fat Princess DLC discount. I figure with other stuff down the line I'll come out ahead over the 15 months. If not, I won't sign up next time.
Also, I honestly don't mind supporting a decent service in part because Sony has not charged us to play games online, which is a concept I hate on principal alone. I like that my entire gaming catalog won't be ruined by not signing up again. Yes, I may lose access to a few "free" games (I can simply by them individually if that happens), but I'm not forced to subscribe to PS+ year after year with the threat of losing access to a major function of most of my entire library.
