I only do what I like, it's not for other people as such and even if it was, there are as many people who like as don't.
The day I have to do something I don't like is the day it becomes a job and not a hobby and I probably won't do it.
As to that website it's easy to pick out poor pictures and **** them off, there are millions on Flickr and other sites. Normally I find the people with these attitudes can't actually produce anything better and in some cases much worse.
As to types of pictures i'm finding I take what ever takes my fancy and publish whatever I like, I don't mind if you don't like it or someone thinks having a camera doesn't make you a photographer.
I play golf, a 7 handicap, turn up at any golf course and you will see pepole with £1,000 worth of gear and can't hit the ball for toffee, doesn't not make them a golfer just not a good one, however they still enjoy their hobby and have a good time.
I have found photography much like golf, you have people with all the gear that suck, you have people with old gear that are great and then there are a mismatch of people that don't really care if they are good or bad just that they are having fun and some will have expensive stuff and some not, imo they seem to get the best deal. Then you have the pro's many who have the gear and the skills but don't actually get any fun out of doing it all. I am the I do what I like and enjoy doing it
Just to add I have no issue with people saying I don't like that shot or this shot and the reasons why, it's more the push against certain types of photography, it comes across as there is only 1 way to do things and if you don't do it you suck. Conform or die seems to be the attitude in some places.
