I kinda like the idea of doing a "What's your favourite?" type thing, people talking about games they are nostalgic about, or still play. I could probably query Twitter for a hash tag and links to the site then display them on a page here.
Yesterday I added webshare to the site, in browsers with javascript and webshare support. It's is currently the a button with a ♥. I think it mainly shows in mobile browsers, and acts like native sharing. Hopefully it could encourage people to share links to the site. I'm going to shuffle the game pages around a bit as well, when that looks a bit better I'll embrace sharing a bit more.
I also added some Open Graph protocol tags so that when the webpage is shared it can look a bit fancier.
