The Silver Blade Adventures blog is written by Matthew James Stanham, who is also one of the coauthors of Astonishing Swordsmen & Sorcerers of Hyperborea, an old-school RPG under development. The blog is relatively low volume, and is made up of articles and reviews of OSR-friendly published products. The reviews are useful, but for me the real gold is in the articles, each of which ruminates on a game trope or rule (and usually includes a link to a document which compares how the aspect under consideration is treated by the various versions of TSR D&D and popular retro-clones). I just finished reading these from beginning to end, and I’m sure I will revisit them, especially the comparative historical analysis documents.
Further, his right sidebar “Blogs” widget contains one of the better lists of influential OSR bloggers. I’m not familiar with all of them, but based on the (excellent) work of the ones I do know, by association I’m confident all of them are worth investigation. I can’t link to the widget directly, but here is a snapshot in time:
Mr. Stanham also maintains an excellent collection of links to published OSR materials at this Dragonsfoot Thread: Publishers & Products.
