I just got my first cold call from India offering a reciprocal link exchange. Sounded much like those other cold calls we get here for outsourcing Web development and design to India. But this one was asking about a reciprocal link exchange. The call lasted about 20 seconds but I thought I should notify you guys. I prefer the emails, deleting those (if they are not caught by spam filters) takes about 1/20th of the time.
I believe we registered our phones with the National Do Not Call Registry.
