oh wow ... that's kinda amazing you of all people @glyph (given your contribution to conceptart!) Dan and I are constantly using the images you post to communicate more richly using &-mentions

One thing to know about content addressability @dan is that for private blobs (attachments in PMs say), the address is different each time, so not re-useable. I'm 90% sure this is the case. It's necessary, and also a shame because it change the private communication medium quite a bit for me in terms of liberal blob usage
