Dunno much about blogs, mainly because of my inability to read the devanagiri script, but I have found a couple on blogspot. However, I've met MANY nepali's online through flickr and I hear deviantart also has quite a number of nepalese people there.

The Nepali diaspora of flickr are really well behaved and very talented in their photographies. You should check them out.

I am also looking forward to meeting new people over on twitter.
