Typical of what happens with new technologies, there are always unforseen issues and backlash. Now with Twitter. Congressman Peter Hoekstra had picked up the Twittering habit and was keeping his Michigan voters updated on what he is doing, on a very regular basis via Twitter (good, we support that, and good use of Twitter too). So yes, so far so good. So he flies to Iraq to visit the war zone and US troops, and then posts those updated on Twitter too. Oops, suddenly he is informing (his followers back home in the USA) on matters that the travel organizers do not reveal about the trip into the public domain. A possible security leak, certainly. Will these happen, of course, and this is now an issue of learning and some guidelines that should be brought to the attention to all who attend such travel. Its not just Twitter, it could also be SMS text messaging etc. If these trips are kept secret for security reasons for the participants, then even users of always-on social networking services should be aware of it, and perhaps do a Twitter comment before the trip, saying I am now joining a silent period for the travel, will Twitter again when its safe to do so..
Interesting to see the developments with new technologies (and still personally with ky Tweets, I am having the hardest time adapting to and embracing Twittering. I always feel a guilty pang that there are a hundred followers who would like to read whats up with me, and I am not diligent about my updates..)
