Infact I get so much unwanted email from the service and from people I don’t know and don’t want to know. Today, I got so frustrated with the whole email thing, that I shut down the account. Done! I will give them full credit for making it much easier than say Facebook to delete my account.
I must say this is similar to my experience with LinkedIn. I did use it when I left Macworld to show recommendations, but that’s about it.
