Great idea! Congrats on shipping, that's the hardest part! Site looks great. Just something I noticed, images from the blog took a bit to load, and they could be optimized (will also save you bandwidth). I recommend doing this for all images though. Search for tinyjpg or similar free sites, it will compress the images without losing much on quality.

Keep it up! :)

Edit: there are some great libraries to compress images too. e.g. https://github.com/semiromid/compress-images
