pohl is riffing on a classic dril tweet:

> issuing correction on a previous post of mine, regarding the terror group ISIL. you do not, under any circumstances, "gotta hand it to them"

Beyond the joke already mentioned, there's potentially another one, in dril's original comment; there was always a bit of a running joke, with some element of truth, amongst Twitter users that Twitter was terrible and needed to be destroyed. There's a reason it was affectionately known as the Hellsite; Twitter aficionados had a very love-hate relationship with it.

I think you might be missing the clear sarcasm in that HN comment...
