My recommendation for this week's Follow Friday is Heather H. Doherty's Good to Know: A Genealogist's Guide. Heather's blog gives genealogists a look into other fields of study and sees how knowing them can help you find your family.
Heather has only 4 posts are her blog so far but they are all packed full of information. I love how she encourages genealogists to think differently about their research.
Part I - Historical Events
Part II - Terminology & Abbreviations
Part III - Sociology and Behavorism
Part IV - Get to Know Another Occupation
