As said above, it helps the modders. And every once in a while a good, well-thought-out idea can gain notoriety. That happens less and less these days, though.
The truth of the matter is that the Suggestions Forum is what is known as a "sink." Mechanical or electrical components may have "heat sinks" to draw heat off them, lest the heat damage them. Like so: http://en.wikipedia.org/wiki/Heat_sink
So the Suggestions Forum is really nothing more than a "Suggestions Sink." We know Mojang doesn't look at these forums. But if we didn't have a place that would draw in and contain the suggestions, they'd be spilling out everywhere like in General Discussion and Beta.
We can't disallow suggestions. That wouldn't work, and we wouldn't want to try. People have the right to speak their mind, within the Rules and within reason.
Short answer: Because we need a place to put them.
