My account is new so it does look like a straight troll account but I was just having a bit of fun. TBH, as I stated in another comment ITT, wordpress provides a really easy way to test out this concept. I expanded my thoughts on the concept in that comment, but as to wordpress:
I bet reddit is just getting crushed with improvements and the engineering team is overworked. It is really easy and inexpensive to test this concept out without losing developer bandwith. wordpress provides a pretty good CMS (obviously bloated, [standard other wordpress criticsims], etc.) but they can get a tight feedback cycle on this idea and it could successful, but if not, will not be resource intensive.
I generally wish them the best of luck, they need something to work at a monetization level, and I hope this helps as it likely is not the long term solution.
I had a rough first experience with wordpress for a client recently and I just had to vent.
