We could also compare them this way: these days, HN averages 1500 submissions and 10000 comments (or so) per day. Does anyone with Reddit datamining fu know what percentile that would be for a subreddit? How many such subreddits are there? What are some examples?

Of course there are assumptions involved in mapping that to userbase size or whatever, but it would still be interesting.

I think these assumptions are the trickier/error-barriest ones. The other, more directly comparable stats suggest reddit is more than 100x bigger than HN. The comment and post numbers here

make it look like something closer to 500x-ish, give or take.

eyeballing (the purest ancient datamining fu technique) this

puts HN somewhere in the 15th-to-20th-ish top subreddit category by post and comment activity.
