Flexor the Mighty!
18/100 Strength!
These days, I DM my homebrew campaign (which occasionally uses content from published adventures), a bunch of short-form D&D Expeditions adventures, and one Adventure Path, currently Princes of the Apocalypse.
Short adventures are terribly difficult to sell in print these days. Frog God packages its short adventures together to form longer hardcover/pdf bundles (such as the recently released Quests of DOom 2) because it makes more financial sense, and I'm not sure what the distribution is like for the Goodman Games adventures.
There are a lot of short adventures in electronic form, although (as with most adventures) only a few can really be called "good". In some ways, they're even harder to sell than the APs! You buy an AP to get a campaign - and a lot of people find that convenient - but there aren't likely to be that many of them about. When there are a lot of short adventures, the competition makes it harder for one to distinguish itself.
Cheers!
Digital is fine with me since I'll be marking it up and can print out the maps and pages I need. The rest can stay on the tablet. I think AP's like WotC is putting out also appeal to the probably sizeable number of people who just read RPG stuff since they can't game for whatever reason. High production values and all that. Usability is much more important for me.
