While there isn't a ton of information out there in the blog world, and many of them do not stay recent, if you look hard you can find some good posts. Here is a list of the blogs I've been able to find, so let me know if you run a site or know of any others!
I'm A PA - A site from the AAPA, and their blog does update a few times a month, and you could write for them if you have an interesting perspective.

PA Student Essentials - A site run by PA students and the SAAPA
Meghan in Medicine - Meghan is a soon-to-be PA student who is doing an amazing job showing the details of how she's accomplishing her goals.
Reddit Pre-PA - Not exactly a blog, but more like a forum to ask questions to an active community and look up information that others have asked about in the past.
PA Boards - This is a great resource with so many options - podcasts, blog posts, PANCE review, YouTube videos, and even an app!
