As a well-known Stereophile columnist would say, "je ris mon mauvais rire" (I laugh my evil laugh).
OK, I'll daydream a little, FWIW:
HF is a huge, sophisticated, groundbreaking operation. It makes life much more enjoyable for thousands. It should not be allowed to fade into irrelevance because it has somehow developed a blind spot the size of a Mack truck.
At the very least it should hire top-notch developers and deliver flawless integration with Tapatalk or some equivalent. Better, it should deliver a standalone app, which could be based on licensed code. Although there is an argument to be made for a mobile version of the site, which should be easier to run within the kind of app Facebook currently delivers for iOS (they are building a native app now, however).
Also I think HF should not hesitate to require payments from end-users. A buck or two per end-user would cover a lot of expenses, with widespread adoption. Payments could be made in advance too, Kickstarter-like, to crowd-fund the initiative. I'd put in a clam or two for a full mobile experience. Even more to avoid ads, much as I enjoy window-shopping, because they destroy usability on small devices.
Challenge the sponsors/advertisers for financial support too. That will test their commitment to the platform and the community. One of the best arguments HF can use is the value of its large, focused user base in terms of marketing/market research. It probably has no equivalent and they sure would want it to keep growing.
