Winterhalter is not a name that would probably mean that much even to people who have been inside Mars Hill Church, much less to outsiders. However, the pastor is at a church plant spin-off/re:boot of the Mars Hill corporate entity and, as such, might be worth keeping at least some moderate tabs on.
The blog posts linked to below are fairly boilerplate. In fact there's nothing about them that's particularly worth commenting on from the texts of the posts themselves.
But what is pretty new, compared to the sea of blogging done by MH-affiliated pastors and deacons, would be wording that's this specific:

Depending on one's assessments of Winterhalter as a pastor one may or may not wish to purchase the recommended books by following the links. Mileage may vary.
