I think every respectful software shop has a Twitter account nowadays, why not Zeus?
I think it would be very convenient to receive the latest updates (or even may be forum replies ), promotions, new cool features, releases, polls, etc. right on your smartphone, computer, tablet and so forth?
if both george soros and bill gates offered to give me their entire personal fortunes i wouldnt trust ANY ONE of those forums as far as i can throw the empire state building.
