Has the front pages of r/technology and HN become shockingly similar?

Funny enough I recommended this site yesterday to another question but it makes this point obvious as well. From what I can tell people submit to both sites at the same time often:

If you remove the political and non technical articles from HN, yes they are quite similar. There have been a few posts I've seen on /r/technology which I haven't noticed on HN.

They are very similar to a casual glance though as I don't read Reddit regularly I can't say more.

you can also pick up similar submissions on pinboard

I recently self posted to Reddit (startups) and to HN. (And was gripped by self doubt - what if it is a netiquette faux pas)

The reason - the first sites I thought of. I should narrow down to forums that my target niche read but ...

Ps HN got 50 visits and one up vote, Reddit 200 and one up vote. So I need to go to writing school.
