Yeah, I don't use any of these services because I host my photos on my own sites. I do like 500px because it started out looking the way it did, and of course other than linking to photos I find on it I don't deal with it much.

I suppose you're too busy to set up a Wordpress gallery? I haven't looked into that myself but I know they have templates for photo galleries. I'm not sure if you do batch uploads to Flickr or if Wordpress supports that.

Anyway, you have my sincere condolences- see my rant about Yahoo buying Tumblr recently. :/
