I suppose if you wanted it to be a super modern all singing social environment it’s lacking, but I think purely for photos it’s great.
I can store photos, beam them from my phone if I want, I can link to them, and I can have friends who can see my activity and comment on my pics. That’s ALL I want, and it does it pretty well.
There is a flickr app btw, and it integrates with Android so you can take a photo and click ‘share’ and it’ll magic to flickr.
Actually there is one thing I wish it did. If I share a photo with facebook, it just posts a link to it on my timeline, the photo isn’t actually THERE on facebook. I’ve shared loads of photos on fb from flickr but of course my photo albums are empty. It’d be nice if you could copy them over.
