hey add some creative logo, that will make your site look unique. add an option to bookmark the site, so that users can amke it their homepage. and add some fun widgets as well...something people can toggle with when they hang out on your site. and make it a bit more interesting....add some vibrant colours, some goofy-geeky bakgrounds. all the best..
I would say this is a good site to go. The overall design layout is good and content is well-written. Focus on driving traffic now.
