I am beseeching you jellies who have been around far longer than me for this question. How many great migrations have there been to fluther from other q&a sites? I have witnessed two: the great wis.dm migration from earlier this year and now the Answerbag migration. I have also heard rumors and tales of earlier migrations from askville and yahoo answers. Does any jelly know how many of these there have been? Also, how smooth are the transitions usually? Having been through only two, I cannot properly gauge how well refugees from other sites take to fluther.

Disclaimer: This is not meant as a cheap shot or the beginnings of a flame war. I am honestly curious about the transitions.
