I don't plan to abandon the project. I plan to keep it growing into something more than just a handy list of sites. If I can earn a little while doing it, awesome, but it would have to happen organically, as I don't plan to plaster ads all over it, just to keep the lights on. That's not my kind of game.
As soon as I have 100+ sites, I'll be looking at adding a monthly/weekly newsletter which will be covering what's up in the industry, and keeping folks up-to-date about our favourite pastime, maybe a blog section for long-form content, such as reviews, news and community created content (guest posts?).
Let me know if you guys fancy any of that, as I don't want to sink time into something that won't be helpful/entertaining.
If you've got ideas, I'm all ears too! Can't make any promises, but I'll definitely listen.
