Pros
You have the opportunity to have your writing published on a popular website. You gain some work experience in the non-profit sector. You learn a little about advocacy and how to engage with your government. The internship is telecommute so your hours are flexible.
Cons
The Borgen Project expects its writers to draft 2 articles a week, yet they take several weeks to publish. I am on week 7 of my internship and they have yet to publish an article I wrote. It's unpaid. Despite this glaring fact, they expect you to use your own money to send fundraising letters to your family, friends, Congressmen, and the White House. You do not receive feedback on your articles from the editors. Seeing as writing is the largest component of the Journalism Internship (or should be), not receiving feedback means I basically do not learn anything/gain any new skills. They prioritize fundraising above everything. They expect at least half your internship to be about fundraising, which is silly because then everyone starts producing subpar articles. They should really have just fundraising internships as a separate category. You don't hear back from the managers. Every week I submit a weekly tracker and as a response I usually receive: "I got it, thanks!" I would appreciate getting a call from a manager every other week or so to feel engaged with the organization.
