I’m inclinded to agree that £15 a year isn’t much. Also, agree with what rocketdog says about the flickr community, it does seem to be used by pros and certainly enthusiasts, with lots of interaction. I was contacted by a few people wanting me to join their group (based on photos I’d put up) or commenting on my photos.
I reached my 200 photo/vid limit with flickr, but decided I wasn’t bothered about the community, I just wanted to download lots of pics and vid for my family, friends to view and hosting pics for STW etc.
So, changed to photobucket, who allow lots more downloads before you have to pay anything. I currently have 400+ pics and vids hosted with only 14% of my allowance used so far. Downloading is just as easy as flickr and certainly I’ve compared ‘back to back’ the same video and quality appears just the same as flickr. Also, with photobucket you can arrange into albums and sub albums as you like, free flickr only allowed you 2 or 3 albums IIRC.
