That would suggest existing topic to upvote & comment on, rather than add endless posts about the same things.
Voting on useful additions is a great concept, however...... 600+ pages of the same ideas isn't helping steer development imho.
For example, if I search say File Sharing I see over 200 DIFFERENT posts. Each with only a few upvotes.
If you want to see what your users honestly want, now you have to have someone compile the same ideas from hundreds of posts???
Waste of your time & the voters. Not to mention extremely inaccurate. Unfortunately at this point your moderators would have to backtrack thru 1000s of posts to add keywords to implement this in a cohesive manner... So hurry up & get on it before it gets even worse!
