Re: Why WordPress + BuddyPress is going to suck!
Well creating a network (basically MU) in WP 3.0 still requires that same deterrent-knowledge you speak of. Not everyone will be turning this on!
However, bringing this functionality to the masses also sheds light to the project and more developers will be able to contribute to the codebase.
I do agree with you about mass-communities! Not every community is going to be vibrant, but even those BP communities that have 10 active members is enough to warrant BP’s existence.
You should also know that there are a ton of low-quality “sucky” blogs because of WordPress, so what’s the difference if there are “sucky” communities because of BP?
