Here is my current 4e PBP for one of the players that participated in both of my 1-30 games.
Here and
here are the most recent of pemerton's recaps of his homegame (you can find a considerable number of them if you look them up).
Here is JamesonCourarge's first foray into running 4e (he has documented his other sessions as well).
Here is a low resolution (at least for me!) recap of one of my sessions at level 27. I've got several anecdotes from this campaign strewn all over the place but I'm not of a mind to collate them all.
Here is a quick one-off that I ran for Campbell, LostSoul, sheadunne, and pemerton (for purposes unrelated to just enjoying a gaming session). This has been picked up as a Dungeon World game
here (a system I highly recommend for GM's trying to get their heads around 4e noncombat conflict resolution - Skill Challenges).
There are several other very accomplished GMs on here who have posted threads for their games including MerricB, D'karr, the Jester, Quickleaf and many others. I don't have the time to look up their threads but it is well worth a look if you're trying to get your mind around how to properly run a 4e game.
