I don't think any snake could be considered "social". Many species that are popular as pets with regular and proper handling learn to "tolerate" us humans through interaction, but snakes are loaners even amongst their own.
Sure it's great to have a burm or any snake for that matter free roaming - in his/her cage. =) Most snakes require husbandry that is different than the common environment in our homes, which includes being away from hidey holes in your house, children, small animals, etc. An adult burm can definitely hurt children and/or small animals, so eliminating that possibility is really smart. =)
And burmese pythons absolutely get huge. The world's largest snake is a burmese - and as adults, they need a rather large enclosure, room size even.
Hopefully April (who posts as Shelby) will see this thread and chime in; April actually used to work with "Baby" (the snake linked above), so she might have some good experience and tips she can share with on burms.
But oh, I agree, they are gorgeous animals, aren't they? =)
