Seems the one way is to create profiles in relevant places, then use twitter to keep them current. Twitter has all kinds of neat easy to embed syndication widgets: http://twitter.com/goodies. My tweets currently go direct to WoTI, Facebook and Linked In.
I set up Who'd of Thought It in 2010, as a blog and place to share and develop ideas.
It evolved into a small community and forum to post thoughts and canvass feedback, with me entertaining the notion of perhaps collaborating on and publishing some of the content to a wider audience. After gathering some initial traction (there are some novel concepts in the archive) other ventures took precedence.
'WoTI' now serves as a occasional pleasure, scrapbook of ideas and guest posts from those who dare. But never say never!
