However, I'd argue that having the filters actually pushes for curation. Since there are more steps to make a picture "interesting" before posting, you're most likely to pick more carefully. In a way, because you're using filters, there's an expectation that the picture should be interesting.
The other thing is that, honestly, using filters has produced pretty nice pictures for me and I'm taking more casual pictures as a result. Maybe I'll regret not having the unaltered version later… but in the meantime, I made some pictures that are more interesting than they would have been without any filters. The banality of some subjects gain from the filters, even if they're canned. For example, instead of just posting "Painting today", I took a picture of my painter tape, applied some filters and posted it with "Painting". I wouldn't care about that picture otherwise, but it looks good and adds a little bit of something. (IMHO)
But, as with all things, this fad will most likely pass.
