I did date quickly after my ex left - about three months to be exact. BUT - I had been DBing for ten years, we had reconciled and then he went off the deep end again, there was no hope of reconciliation nor would I have taken him back at that time. I had peace in my heart that I had done everything possible to save my marriage and I had already gone through all the DB growth process. So, just saying everyone is different in terms of when they will be ready. The important thing is not to date when you're desperate OR when you're still stuck on your ex or there's a possibility you might reconcile.
