Submitting homework assignment. Hopefully it works

Hi @JamieMihoko, I think the issue is simply that the blog link needs an explicit "http" in front of it, like you have for the twitter link. (Markdown code is particular about those things, whereas web browsers are not.)

To make a fix, simply follow the recipe:

(Make sure you don't edit your file to make the fix until step 4.)

Hope that helps!
