It's probably just as easy to send an angry email. But something a public medium like twitter doesn't really allow is subsequent apologies - people are often afraid of admitting guilt publicly. Running a quite large site, we get our share of angry support (email) tickets. Although we don't have to take any shit, we are generally nicer than we have to be ("Please find some mental counseling. Issuing death threats over not getting your ticket answered within two hours is not normal.") and received our share of apologies. We also regularly get shit thrown our way via twitter, but don't expect any apologies there.
