Judging by the amount of Lavalantula stuff on Trey's twitter, I'd give a resounding "probably"

I would disagree with that sentiment, immensely. It might be true for some people, but those aren't the people you want as your heroes anyways.

As weird as it might sound, there are a couple people I've grown to respect immensely, more than I ever could have thought because of what they're doing on twitter (I mean, generally it's twitter used as a channel point for news about all the cool shit they're doing elsewhere, but point stands). Just off the top of my head the amount of charity work that Misha Collins does (Yes, the Angel guy from Supernatural), plus planning/hosting GISHWHES every year that brings together people all around the globe, it's awesome, and Misha is always an incredible cool and humble guy. And I'd know about none of that without twitter.

And hey, failing all hope in the people you look up to, there's always the innumerable amount of joke accounts that are always good fun.
