Same thing I noticed. All 4 accounts (which were the only 4 comments in this thread earlier) were created just an hour or 2 before this post was made and the only comments those accounts have posted are in this thread. Couldn't be more obvious/idiotic with the shilling.
I don't see why the company couldn't have let their product speak for itself instead ruining their rep with this underhanded tactic.
Also, their site says the public beta opens in 11 days.. Why not wait till then to show HN so the developers here could actually try the product themselves? Some brain-dead marketing from kobra.
