It's a nice bonus that they can interact with each other, but microblogging and link aggregation are two different things, no need to make them more interoperable than they are.
Sure, American advertisers don't like that, but foul language is all over Reddit, so that's not something that will drive advertisers away that would otherwise consider advertising on Reddit.
Doesn't matter, it drives user engagement and website traffic. Easy way to show to advertisers that Reddit is very much alive. They don't care what is drawn, as long as it's nothing illegal or bad for advertisers. People want to spend 24h to write "fuck u/spez"? Sure, whatever.
wtf do you do to those wristbands?
