IMO, Smashing is mostly typical blogspam with very occasional nuggets of good content. If you browse HN and some of the Reddit web/programming subreddits even somewhat frequently, both Smashing and tuts+ are pretty useless.
Yeah, I'm still trying to find the good dev subreddits. You get downvoted in /r/webdesign over some really pathetic crap but it seems to be the most active - any suggestions?
