That was me, and I was thinking of that conversation as well. It's kinda sad to be proven right in this way, but it's true. Comics are a business, and what sells stays and what doesn't sell goes. Periphery books that don't have a high enough profile or enough involvement with the metaplot of the Marvel Universe are always going to struggle. Fanbases don't just materialize out of nowhere, they have to be built up.
You can't just take a good idea or character and throw them out there in an ongoing title and expect it to work. You have to establish them first in a book that gets a lot of readers, build them up so that they gain fans, and then when they reach a certain level of support then you can do miniseries with them. If those go over well, eventually they might have the fanbase needed to support an ongoing. Maybe. If not, all you can do is promote and feature them where you can until they are strong enough, and hope they reach that point. You can't just throw a title out there and hope for the best, but sadly that's what Marvel does far too often.
What Marvel really needs is a "jump" sort of title. They've tried it before with Marvel Comics Presents, but they failed to make it last. To me that's because they failed to remember what made the first one work --the book was led by a feature story that had a hot character (often Wolverine, but in that day also Cable, Venom, Ghost Rider, etc) to anchor the book and make sure it would sell while the rest of the book was interesting stories with lower-tier characters. If Marvel was smart, they'd go that route again, making the lead feature "Tales of the Wolverine" or some such and sell that instead of a second (or maybe even a first) Wolverine ongoing. The Wolvie-heads will buy it, keeping it out of cancellation, and Marvel will have a place to introduce and showcase the smaller stories that creators want to tell and fans want to read but that aren't strong enough to support an ongoing. It could not only be a launching point for new concepts and a home for weaker-selling but still interesting material, it could also be a great tool to help Marvel maintain and foster a sense of a living, breathing shared universe. A place where there's more going on than just what we get to see in the lead titles with the established names. A place where you might get the first glimpse of tomorrow's hot titles, or get to see stories you otherwise wouldn't.
It sure as hell makes more sense than just throwing new titles out there to drown.
