It's totally hindsight driven, but the fact that he started every HN comment with the same "Jonathan here" type canned greeting should have probably raised an eyebrow.

(amending this: after reading up a bit I don't agree with my own original post. It's a very odd thing to do -- I don't ever see anyone on HN post like that -- but he's not a fictional person or anything like that.)

i just read that as mildly n00bish behaviour - he came to hacker news simply because the story was posted here and he wanted to make sure his posts were known to be from him.

FWIW his account is over a year old (though not very active).

It looks like the same thing that happened this time. Someone posted an article of his to HN, then he created an account here to comment.
