Rexi posted:Oh, and, why is everyone thinking that Ted is H just because of how he spelled definitely? That computery woman said that they has been analysing posting styles, so surely he was just copying what had been posted before?
Well; Mercurio deliberately made sure that "H"'s old message including the word "definately" appeared in the "Previously..." montage at the start of the episode just so that fans would jump to that conclusion! 
However; every "clue" so far suggesting that Hastings is "H" has an innocent explanation. As you say, they'd analysed the posting style, but also get this: I did a quick search online, and apparently "definately" is currently the most common misspelling in the English language!
I guarantee you that Mercurio didn't choose that particular mistake at random...
