I lurk on Facebook under an alias as they won't accept that this is my common law name. I see no reason why we need our real names here. Let's not replicate Facebook - I much preferred Google+ and MySpace.
Friendica
All things about the facebook alternative Friendica.
I personally don't have an issue with it. I put my real name as my display name because I want people to be able to find me. I trust it more than I would trust facebook with my personal info.
My name is Miles Edward O'Brien, and that's all any online entity will get. Anything beyond that is outside its "need to know"
(never give any online entity your real name unless you would trust them with your house/car keys)
It’s interesting because the different formats will give different context to the posts. Overall though I think the tone of the comments will even out as the posts will be less echo chambery.

Don’t put personal information online, always use an alias
