This is a little off topic, but I can't stand sites that make me click 'next' 10 times just to read their article.. It instinctively makes me not want to read it.
Quite a few of these were check-in/advert type applications. I can't make myself even try these things, like foursquare facebook places, etc. I just don't like the idea. Anyone I want to know where I am, knows where I am. Adding lots of ways to sell me stuff after I check-in, or just straight up following me around tracking live for marketing purposes, solidifies my resolve to not use these things.
I can't say I would absolutely need any of these things, but their uses seem like they would work well in special cases, like some with some big company or something. I suppose there is a market for these things, but overall I'm not sure how necessary they really are...I think I may just not be reading about them detailed enough, nor do I want to cut down on the hard work of these developers, but how necessary is the next step in social TV, or something..
