Brightkite is one of the many Location-based social networking companies out there.

Brightkite has a handy sms updating feature (which many social networks do I am sure) BUT they have added a setting called “Quite Time” which specifies a block of time (like 3AM – 6AM) when you don’t want them sending you sms messages.  Simple and straightforward but oh so useful.

I hope they will allow multiple quite times to be set; so if for instance I am always busy between 14:00 and 17:00 as well as between 3:00 and 6:00 and don’t want to be disturbed during these times I can set quite times for each.
