identity on the web

Shouldnt i remove my identity from the internet?
Got a phone call from someone who found my CV on Google. Rang to see if i was interested in Contract. The CV is my market stall, so the caller is welcome. Some sites i use however do keep my identity and contact number well out of sight.
I've no real worries about my real name being found. I will use a alias like sievpeople because it gives some branding away from the corporate me. Im still not a twitterer or facebook tag, so no need to pass round a list of friends of sievpeople or other social network links. if they do get set up they are there for occasional use.
came across this article about the different types of blogs today -
http://blogs/telegraph.co.uk and look up Dan Monsieurle

and about Tumblr which i might try next
