Nah its just that people who are experiencing issues are 'louder' than those without!
This!
I heard about how it was impossible to be in the oblivion forum for the first few months because of all the whining kids, and I can see, that it's the same here. A lot of the members are joining the forum after or just before the Skyrim release, and it seems, that these are mainly the complainers, but the worst of them will dissapear again quickly.
The game does have some errors, and in an openended game like this, it's a little random where these errors will occour, since there are an infinite number of ways to play the game, and like it was said playing it after a guide should probably give very few errors, since it's most likely played the way the programmers thought the game should be played, and therefore the best tested way to play the game, while people playing the game 'out of sequence' are more likely to encounter bugs. The devs had maybe 10 testers, now there are 10 mio testers, so it is to be expected to encounter some bugs, the devs didn't find.
So there is bugs and appearently the ps3 players have gotten most of them. But on PC I have only encountered 2 questbreaking bugs (both solved by my friend google) and a handful of crashes, but I don't consider it a major problem with 100 hours played. Also a lot of the reported bugs are not bugs but simply how the devs thought the game should be (f.ex the smithing tree is not broken just because someone doesn't like it or have found a way to exploit it).
I know that other people has encountered more bugs than me, but it seem most of the complainers, just creates a profile to start a flamewar after the first small error they encountered, and they are really just spamming the forum.
