Anonymous and http://en.wikipedia.org/wiki/Anonymity works well along with First names only.

I know most say, you should really use your real name But with the internet the way it is... Do you really want to?

eBay and Google suggest "Not". Yet people insert their photos all over the place, fully searchable, by people you just don't know "yet" and might not want to.

Just that little word of caution as many internet marketers use http://en.wikipedia.org/wiki/Pseudonym for business and personal reasons.
