I thinke they are nice, so long as the photographers dont stick them in your face they are supposed to capture the feeling of the party therefor i dont like photos where people pose and such things.
Then there is a difference between amature photographers and pros. Of course there is no wrong in taking some pics of your friends, but taking pictures at people you dont know and then publish on internet is not ok. If you take pictures at someone you dont know, it would be nice to ask them if they agree having their pic published.
oh what a lot of jibberish...enjoy
