The free account is great for testing out how it works with other services you're using but I do wish there were more options to customize what shows up in my feed (I'm looking forward when they add RSS support).
There's also no way yet of filtering which posts appear at top so that if something isn't interesting or relevant right now - we can still see new stuff from others later down! It would be nice though as sometimes certain feeds are particularly good sources even without putting any effort ourselves :) If anyone wants an easy-to use service where their friends/family could upload all sorts things then this will suit them well enough until those people get bored ;) We've been able share links between our team easily across different devices because everything gets uploaded via put files rather than emailing around folders full of pictures etc.
