Sometimes, when people go to certain places like a library or at work to check on the forums for these announcements, the library/workplace/wherever blocks all message boards, games, and everything else pertaining to Second Life. If there were an email system, and the place they were working allowed email access (which they most likely would), then they could spend their usual time of pretending to do work on checking for their questions they've been wanting to ask or asked in the town hall email!
Note: The maker of this post is not liable for bosses or co-workers coming in and seeing you 'working.' This can get you fired and is also stupid since there is probably a deadline for whatever work you should be doing.
