Reddit as a whole, sure.

The front page itself though? I don't know how others use it, but my frontpage is populated by my favourite subreddits, which are luckily mostly free of politics.

TBH I have no idea how the majority use Reddit, but don't confuse the front page with all of Reddit.

(As a side note, yesterday I went on /r/The_Donald out of morbid curiosity. I'm not sure what I expected, but it was rather shocking).

I've not read the reddit "frontpage" in years. I do run into it when I'm not logged in, but I don't look at it at all.

So it is likely to be infiltrated with marketing disguised as news & comments. Lots of agendas. Not sure it is as relevant as you think.

With a demographic that is the inverse of the "voter turnout by age" graphic though [0].
