There are just stacks of Social Networking sites so how do you pick one? Which ones are useful for the professional when you have a job to do? Which invites do you just delete a spam?
I find Linked in useful, and of course this site. But have not seen many others for general use. I have been spammed by Plaxo and Naymz but just deleted them.
Some friends of mine are using http://www.xing.com/ but I've never tried it. I am planning to give it a go..
Will let you know if I find it useful or not.
I am in twitter, linkedin, facebook, and myspace as well as maintaining a blog. I agree with Leslie, that if you are in too many of them you can't accomplish anything significant. You have to limit your approach.
I was thinking of making the Ning site (this one) a resource site only, but recently there has been more community interaction in this environment. I also like the public nature of this site.
We will keep things really simple, NIG and Linkedin
NING seems to be trying to turn itself into a Facebook with the new www.ning.com dashboard page.
