There are plenty of reasons that Zimbabweans might want to get into a time machine and go back a decade, and the throttling of email is just one of them. I just spent some time reviewing my email accounts and subscriptions, in preparation for the move, and whilst checking my mail from Zimbabwe, including lists and email groups, the stats were remarkable.
Over the past four years there has been a massive decline in the amount of email generated from within Zimbabwe - at least mail that I get - and to me the reasons are simple. People have left the country, many feel afraid to comment about what's really happening, because there is a real fear that mail is being looked at by the Zimbabwean intelligence community, and the cost of email, mostly via very expensive dial-up.
I'd be interested for other takes on this. 'Zimbabwe intelligence community' - now there is an oxymoron I had not seen before.
