MG Siegler:

Yes, I find myself tweeting less now that I’m living abroad. My assumption is that it’s mainly related to the time difference (8 hours).

Felt the same way when I travelled in Europe.  But not just Twitter-usage. iPhone usage in general dropped significantly. Partly because I was hanging out with family, party because people around me used phones/technology in general a lot less.

And yes, I was fine with that too.
