Elgg Community Groups ;-)

Interesting..;-)
about 50% of groups here have only 1 or 2 members and
the top 21 groups have between 100+ and 1200  members..
I'd be curious / interested to see (realistic) opinions on
why people join various groups,
how they participate,
what they benefit,
what they'd like to see changed...
call this..... a little exercise in studying "social behaviour" of elggsters ;)
