Actually that's not quite true. While many single issue parties vanish as fast as they came, the greens here in Germany started as a single issue party, and now get over 10% in elections. OTOH, they aren't a single issue party anymore.
But I believe it will be the same with the pirate party. Limiting themself to their "core competencies" at first, then with gaining experts for other areas slowly expanding to these areas.

Actually, in Germany you still have warranty even when modifying the device, as long as the defect wasn't caused by the modification. The problem is proving that, and doing an expert testimonial costs easily more than the repair itself. But if it proves that the defect wasn't your fault, then Nintendo has to honor the warranty *and* pay for the testimonial.

Instead of fixing fundamental flaws like the the sorting algorithm, they chose to add new features. So OO 3.0 is still no viable alternative to MS Office :/.
This is an over 4 year old "feature request". Currently marked as "to be fixed in OO 3.x".
