I read it last weekend on the New York Times website. It’s about a new gadget site to be called GDGT starting this week, developed by founders of other gadget site successes. Get this:

Their new site, called GDGT, will open to visitors on Wednesday. It differs from Engadget or Gizmodo by aspiring to be a gadget-oriented social network. Users of the site can create profiles and specify which consumer electronics devices they have, had or want to buy. Then they can talk about those devices with other owners, discuss new trends and tips, and decide how and when to replace them. (Emphasis mine)

Granted, Twitter changes everything, Facebook too, and Ning is sensational. But please (that’s a three-or-four-syllable p-l-e-a-s-e) — when does this end. Are there infinite successful new ventures out there from just taking any common interest (like gadgets) and making them into social media sites instead? Isn’t there a saturation point?

Take my case; and I’m getting older now, I’m hardly the advance guard. But I have username and password for three of the obvious mainstream social media sites, plus groups including Entrepreneur.com, Smartups.org, asbdc.net, the Business Week social site, and several others I can’t remember.

And that’s the active phrase there: “several others I can’t remember.”

I love gadgets. My son-in-law Noah and I exchange links and such about gadgets all the time. But the last thing I need is yet another new site, with another new password and username, that I’m supposed to be checking for messages. Not that username and password are a problem — plenty of tools for that — but that’s just not going to happen. It’s not just logging in, it’s finding the time and inclination to log into all of these special sites.

And maybe it’s an overdose from my business plan marathon last Spring. Every other new business is building a new social media site to bring people together.

And I just don’t think that’s going to work. Build a group in Facebook, or a chat group in Twitter, or something else that uses the ties and links we already have. Don’t give us another social media site.
