Those issues you point out ("that reddit has") seem to be common on all medium/large platforms. One word comments like "first" and "this" were common on sites like digg, long before reddit came along. And spelling/grammar mistakes are older than the internet.

The comment section of Digg was very different from Reddit. The Digg redesign was the original reason I ended up moving to Reddit.

Their were some one word replies and grammar mistakes but it was certainly not the norm in the subs I frequented at the time.

I can't say much about other social media sites, as Reddit is the only one I have used with any regularity.
