Every day I am being told to sign up for Tumblr, Yammer, Friendfeed, Plaxo, Last.fm, ping.fm or the hot social-media tool du jour that happened to get mentioned on Mashable.com. It is like a social-media arms race. Each one of these new tools is like a cool new night club. Hot today, gone tomorrow, replaced with something else.
