I was looking for a term for someone who is addicted to a Q&A website but I came up with general terms like nethead, cybernaut, netizen, internet addict etc. You can think of adjectives like contributive, helpful or even devoted but they are also too general and they don't cover the "addiction" and "internet" part of the question.
Although, I'm tempted to call this person fanatic:
Anyway, I think there might be an online slang term for this specific type of person. For example, there is ask-and-run for someone who posts a question on a Q&A website and never checks back. (Related question: What do you call a Q&A user who posts a question but never checks back?)
It seems like it is a common phenomenon as there are a lot of Q&A websites nowadays:
There are questions asked related to Stack Overflow addiction:
Quora has a section for this phenomenon:
There are questions on Yahoo Answers about how to stop Yahoo Answers addiction:
So, is there any online slang term for this kind of user?
What do you call a person who is always online on the Internet?
