Yes of course if you intend to work for Fluther, or if there’s a request for a list of hobbies. Otherwise, considering participation here as somehow qualifying you for employment will almost certainly cast doubt on your reasoning skills.
I would also wonder about anything you may written. Unlike facebook, most people don’t know your real name. If they look up your alias, is there anything you said that may not be flattering?
No. There would be no credit. You’re just in here gossiping. I mean, how good would that look? It’s like putting the fact you have 680 friends on facebook on your resume.
I would only ever do that if I tried to work for another q&a site. Say like if Auggie ever wants to work as a paid manager or mod for some big community site, then she could put Fluther as past experience in that field of work. But there is no benefit in putting that on your resume if you’re gonna apply like for a factory or just about anything else.
