Thanks for the write up @jdm :)

Just updated some links in my gsoc repo to reflect current state of things.

A suggested addition: The ending lines of this post can also talk about the upcoming GSoC'17 projects (if any) for Servo and we can probably link pages, like https://github.com/servo/servo/wiki/Summer-of-Code-projects so any one likely to participate next year can reference this blog post.

It is optimistic of you to believe that we have begun any GSoC 2017 planning ;)

Added writeup for @izgzhen. Feel free to edit.

[jdm]

I'll post this once @izgzhen approves.

[izgzhen]

It looks good to me. Thanks!

I checked the blog and found that the section title looks way much big.

Maybe we can change # ServiceWorker support etc. to ## ServiceWorker support or even smaller one

[jdm]

Fixed.
