Why does Advanceshipping have so much activity recently?
I think, simply put, it's because we actually care about our ship. Seriously. Contest, Pearl and other ships are popular, and a lot of the time, many people are simply jumping on the bandwagon where popular things are involved. Advanceshipping has never been the popular choice (compared to other Ash ships), so Advanceshippers generally have something different that draws them in and keeps them there. Contest would never be able to 'wipe out' Advanceshipping; it'd be like the Earth trying to wipe out its moon. All we really needed to come back into focus was a spark. I don't know who or what caused that spark, but the 'why' doesn't matter too much, because it's happened.
We're back, baby. xD
EDIT: Since I got a negative comment about it, I might as well clarify. I didn't mean that nobody cares about other ships. That would be absurd and asinine. I meant that a large number of people simply like certain ships because they're popular, and that the care/don't care ratio is larger for Advance than most ships because it isn't as popular (and thus its members are more likely to have something that makes them care). It's simple sociology and probability, people. I only meant it in the most technical sense. Maybe this wasn't the best way to say it, but I didn't mean anything negative or disparaging about it.
