It's always a good idea to have one life not connected to the other life. If you're doing bad things, it's better not to have any info about true you on the web. If you're doing nothing but good and want/need to have personal info easily found for business reasons or whatnot, then it's good to have that for everyone to see.
I have my "hacker" life, and I have a regular guy life. Both do not interconnect on the internets, but relate in real life.
