twitpic vs trelijah vs posterous

How do you know which blog / photo medium you want to upload your random photos to?  I've really never made the clear distinction besides the fact that when I want a good clear picture of it, I upload it to (via 's services) but if I want to give people instant gratification on twitter, I use twitpic.  Now I'll just have to connect my posts here on posterous and blast them out that way.  Maybe I can even tie my trelijah blog (or retire it) and just go posterous main stream.  What you think?
