bloggavore
Just as a herbavore eats veggies, a bloggavore is a person who consumes blogs in that she/he reads them, but also sets up new blogs and recruits others to read and write on them.
Jane started her internet life at work with emails, but pretty soon she got into the hard stuff like facebook, tumblr, and setting up her own webpage where she couldn't go a day without writing things like 'I am Jane, and these are my thoughts." She'd become a bloggavore.
