You can find my primary blog here:
http://ntang.tumblr.com/
I post frequently there, generally quick thoughts, links, photos and videos, etc.
Longer posts, esp. work related ones, go here from time to time:
http://nicholasytang.wordpress.com/
I'm also trying out about.me as a centralized "profile" page:
http://about.me/nicholastang
And finally, my professional profile is available on LinkedIn:
http://www.linkedin.com/in/nicholastang
Phew!
I may try to "syndicate" some/ all of my posts from Tumblr or Wordpress over here, but for now, this blog is more or less on ice.
