[Air-L] Literature on dimensions/attributes of online communities?

[Spencer P. Greenhalgh]

Hello all,

I'm beginning a project that is focused on making distinctions between 
different Twitter hashtags based on the type and/or "amount" of 
community that is present in each. Because I'm relatively new to online 
communities, I want to make sure I'm not missing important work in this 
area. Are there any resources that you would recommend for thinking 
about what makes up an online community and what distinguishes different 
online communities from each other?

Many thanks!

Best,

Spencer
