Some way I also joined LinkedIn and have started receiving the same kind of requests. I know even less about this one and can't even remember when or why I joined. So, I have some social media decisions to make. Ignoring requests and the possible negative ladders of inference that may result is not what I want. I've decided to try and change my behavior, not a new year's resolution, just a positive step in my social media image.
By the way, have you visited Tahoma's Facebook page? I think with over 20,000 people in the city plus the thousands in our system living outside the city we should have more than 2,674 followers. If you have not yet joined, please do and let your friends and neighbors know about it.
