I posted comments on Dragonsfoot, here they are with some amendments:
I'm glad they stepped out and put Dark Tower on the list, but where are the rest of the non-TSR/WotC mods? More on this below.
I won't quibble with the order, except Ravenloft #2? I'll give that mod props for design and influence, but it really isn't one of my favorites. Belongs on the list, but not #2.
They got the vast majority of the adventures I would have put in my top 30. I think they cheated with the supermodules, especially since many of the supermodules aren't in exactly the same form as the originals, and the originals are universally better.
The omissions:
B1 In Search of the Unknown - the only omission I'd say was glaring, historically significant, unique in design, and great to play to this day.
B5 Horror on the Hill - under-rated even among grognards, Niles' best
B7 Rahasia - Hickman's best work, IMHO, better than RL or DL.
Caverns of Thracia - better than Dark Tower, IMHO, and Paul Jaquays best work.
The lack of representation for the British designers is disapointing, only U1. B10 or one of the UK's probably should have been there.
The ones I question:
Return to ToEE and ToH? - They couldn't find any other 2e or 3e modules that weren't based off of an original for this list? Standing on the shoulders of giants and all that...
L2 Assassin's Knot - I thought L1 was significantly better.
DL1 - toot, toot, chugga-chugga, whoo! whoo! Important historically, but not one of the 30 best adventures of all time. Hickman and Niles each had better work - see above.
Firestorm Peak (2e), Forge of Fury (3e), Dead Gods (2e), City of the Spider Queen (3e), City of Skull (2e) I don't know enough about to comment.
I find it funny that they didn't name a single independent (non-WotC) 3e module. I bet if you asked the 3e fans, they'd tell you Necro and others have put out better 3e adventures than the three WotC products listed.
I think 2e is over-represented and (O)D&D and probably 3e is under-represented.
