A note on social networking site invitations, endorsements, reccomendations, etc.
I generally send a note like the following back, but in some cases I don't have a current email address and/or the only way to respond is to actually join the site and sign on, which I'm reluctant to do.
I appreciate the thought behind the invitation, endorsement, reccomendation or such, but I have have been keeping the entire social networking scene at arm's length due to time considerations. I am on LinkedIn, but only to the extent of providing a link to this site. I spend far too much time on the computer on other-than-writing things as it is and am starting to get very ruthless with myself about time sinks. But rest assured that I'm still your friend. ;-)
