Dunno if you were around then, but people on Digg acted the same way toward Reddit before Digg crashed.
If we stay on this platform and continue to grow and create content, then when Reddit again does something to annoy its years (they probably will), we can be here to take advantage.
The downside is that every great growth in users will affect the platform/site culture, not always for the better. It depends on the users and the size of the migration.
