I deleted my Twitter account, LinkedIn, and Google+ a couple of years ago. I also Googled myself and slowly removed myself from every other service I haven't used in years. Facebook was the only one I kept as I get a lot of value from it. The only server that has crawled back into my life is Google+, and only for one reason - Android. It's the easiest way to backup all my photos. Not to mention the fact I also use Youtube, Google Music, Gmail etc. and it's only a matter of time until a G+ account was forced on me again. However I don't post to the G+ account and I think I've only followed one or two people.
