I definitely think it has a chance if it moves in the direction of being reddit like. However, I think having a mobile app is a major factor in bringing in more customers. Just my 2 cents...
Lets first get a mobile app and get LN wallets to integrate it like Breez, would also be great if there was more integration with other social like fountain app build a bitcoin ecosystem
I don't think a mobile app is a big deal. The big deal is that we speak mostly about Bitcoin. As long as this is a Bitcoin forum we will only draw from the existing Bitcoin community instead of drawing people from the outside into SN (and thus Bitcoin).
I actually asked this question a few days ago, haha. I got some good answers about why that doesn't need to happen. Scroll down a bit and you should see it in there somewhere.
Edit: Actually, someone posted the link already. Guess I should have scrolled down first.
