what do you call the internet people?

As I told a story to my friend Greg Q, for the umpteenth time I had to stop and try to figure out how to describe someone with whom I have a primarily web-based relationship. We decided it was time for there to be proper names for those folks, so here is what we came up with:

Someone you would identify as a friend: WeBFF

I was so sad when Buffy moved away, but between Facebook, Twitter, Gmail Chat, and Goodreads, now I feel like we're WeBFFs.

Someone you would identify as a friendly acquaintance: Interpal

Can you believe my interpal was in a flame war with Billy Joel?*

Someone you would identify as an enemy: Netesis

I always knew I didn't like her, but when she tagged me in that ugly photo, she officially became my netesis.
