I just saw this website and thought it was worth sharing with the GO-GN community.
This is a (CC-BY) blog which draws together a lot of resources for PhD student and personal testimony from doctoral candidates. There are regular posts going back to 2010 and the comments suggest that there is a large community of readers. There are stories of failure as well as success, with a lot of content written by students. There are several new posts each month, so there’s a lot of content there.
Navigating the site isn’t all that easy – there is no search function – I had most luck exploring the tag cloud and monthly archives at the bottom of the page. There is also a Twitter account you can follow.
