There is a young man Michael Makovi (age 22), a talmid in Yeshivas Machon Meir who recently began blogging. He has many thoughtful comments and great scholarly insight that should be publicised to the broader public. Please follow along, his blog can be found here .
In particular see his post on Saving Gentiles on the Shabbat, it is the most thorough collection of sources on this topic I have seen to date.
