twittertariat 

Those ranks of users whose comments go largely unnoticed by the world outside twitter. Below the twitterati but, of course, above the lumpentwittertariat.

No one reads my tweets - I'm a card-carrying member of the twittertariat.

Twittertard 

A Twittertard is someone who cannot decipher Twitter code or blemishes it with their idiocy.

If you have trouble with @, # or cannot say anything constructive, you may be a Twittertard.

Twittertary

A commentary that is delivered via the social media site Twitter. This can be a sole endevour or a group one, wherein person(s) live on Twitter view a movie, television program, etc al. and provide a running commentary. The latter can be trivial based, riff based, or opinions on said program- though it will usually be a combination of both.

1. A group of people arranging a viewing of a movie online and by hash tagging or via a Twitter group deliver a running Twittertary of said movie.

2. A lone viewer via Twitter provides a running Twittertary of a currently airing program via hash tagging.

twitterstar 

People who rely on having a large number of followers on twitter as a form of social validation.
They usually have a verified account, think they are hip and cool, and live in an echo chamber.

"He tweets about something he likes, his followers cheer and nobody can disagree"
"That's what we get for being around a twitterstar"
