Twitter for Travel?

I've recently signed on to Twitter (http://www.twitter.com) and you can follow me (s0mebody, please) @Westmount Writer and am discovering some travel deals advertised there. For instance, Jet Blue Airlines is supposed to post deals on Tuesdays that you can follow as Jet Blue Cheeps (cute, yes?)
A few other airlines, travel companies and writers are also listed. For a time I was being followed by a site called @London England that was supposed to be posting discount deals every day in London. When I checked a couple of days ago there didn't seem to be any activity--perhaps they were delayed by the riots?
This is an experiment with Twitter--am trying to figure out how to link posts for this blog to Twitter. Not sure how it will work out, but any source of travel bargains in these economically difficult times is worth checking out.
I would be pleased to hear from anybody who has found good travel deals through Twitter. I suppose it could be especially useful for people on the road with their mobile devices.

International Phones

I've been checking out international telephones recently, and decided to go with one called the World Phone offered by http://mobal.com. I ordered one but have not yet received it. The phone got good ratings on internet surveys, so I'll see if it lives up to the hype.
Communications while overseas is always a quandry. I considered taking a laptop, but decided that it is just too heavy. And having had my laptop stolen recently, it is also an added worry. I will just rely on internet cafes while travelling. I also thought about getting a Netbook, but on looking into it found it would cost almost as much as the laptop by the time it is equipped with software, and would I really use it when I'm not on the road?
Being a Neanderthal with no cell phone or smart phone, I did not have the option of putting international calls on a regular cell phone plan, as I have seen some people do. And overseas there is always the problem of different electric current and different plugs, just to add to technological hassles.
Anyway, I'm looking forward to trying out one of these world phones and will let you know how it works out.
