Some glitches are practical, and just fun to use. For instance, I try to go to Pictochat often when I'm in the mood to use Kirby. There, I can do his Earthquake glitch, which is just fun... Paul doesn't let us go there anymore though
Apparently I'm good enough with Kirby without the advantage of being able to glitch. Other than that, I don't bother with any... Some of them are just tiresom to time correctly and such.
