One thing good about it is more people are pouring their ideas but that is also a downside of the forum. People are easily distracted and go off track rather quickly.
But topics on the forum are separated from each other (and if one thread strays from its topic, it can be split), so it's easy to only read the topics that interest you.
And again, trolls...
With proper moderation, these can be kept in check without too much trouble.
