I'm certainly not opposed to a way to make personal aggregate.......things, but the problem is these people want it to be done by the service/devs/whatever. They aren't asking for an ability to pick and choose communities to build a personal "super community" for themselves client side, they want all the c/aww's to be automatically pulled together by a central authority - the thing they're fleeing and came here for the lack of.
I've heard people are working on 1 for 1 Reddit clones, and I'd really like to see those people just go support those projects instead of getting mad that the thing advertising a lack of central authority has no central authority and demanding devs "LiStEn To ThEiR uSeRs" and institute one.
