The only problem with letting it drip onto the ground, is that the hose may drip in the path of the rear tire...  For me, that cannister only needs to be emptied once every couple of years.  If it fills up, it can cause problems for the engine, as it will tend to push back into the engine.  If your bike is running rough, this is one thing to quickly, and easily, check:  pull the plug, and if a lot of crap pours out, fire up your engine again, and see if it runs better.  My father discovered his 750 Custom was acting up because its cannister was full; emptying the cannister solved his problems.

Riding in the rain, and running in high humidity conditions, will cause this cannister to fill up faster, according to what I read in my Clymer Manual.  After riding four long days in Canadian rain, for around 24-28 hours of driving time, there was nothing in my bike's cannister (emptied it before that trip, emptied it on day three of rain, got very little; emptied it when we got back home, four days later, and very little came out then, either).  YMMV.  Check it periodically, to get an idea how fast it fills up on your bike, and empty it according to your needs.  Cheers!
