My issue with a mass/community throwaway is there is no ownership. I would like to specify, ownership, not accountability necessarily.

With a community throwaway I can make a thread like this and then I can post three different comments that appear to have opposing opinions, thoughts, etc, that really all come from me. While, to my perspective, that might make for an interesting social experiment (what gets most circles? what gets most discussion? what seems most controversial?) it can limit the engagement of more thoughtful users as they realize there is a lack of ability to trace anything back to any single person, or multiple people. In addition, with a community throwaway, so long as the account has the ability to edit previous comments, no one's contributions are really safe as they could be edited by anyone. It's asking for trolling, if you ask me. It's also asking for community-gaming in a way. It also brings to mind that forum where all the users were really one user - and it brings solipsism to mind too of course.

I don't care so much if you are anonymous although frankly, what I share with Hubski I choose to share with Hubski, and anything I don't share, I'm not going to share regardless of whether I am on my account or on another. That's because there are specific reasons I choose not to share certain things and those reasons aren't actually going to change whether I have a mask on or not. Besides that, I do believe in personal accountability, so I'd rather present myself and my mistakes as wholesale as I can and acknowledge that I've failed in my life. Not hide behind a screen because I am ashamed. I would rather have to raise my face and make people judge me for the whole person I am.

Those are the general and personal pitfalls I see with such an exercise.

Be brave. Also, hubski isn't here to be your confessional. Reddit's great for that. Use Reddit for that. Go on, I understand; it feels good. I've used Reddit for that too, once upon a time. But when you are ready to have a discussion about who you are and what you've done that might have been bad, take it to a website where the people see you for a person. Not a username that is not even worth looking at (which is how I encounter reddit).
