[@jynmi88]Offline and online personalities don't really have to be anything alike, but it would make more sense if they were similar, as it would be easier to keep up appearances.  If I was writing the character (but I'm not, so feel free to ignore this) I would decide what kind of videos they made on YouTube and base them off of a youtuber that did that.  Maybe even combine a few.

I was thinking of making an indie developer, so maybe he could be going to the convention too.
