My first thought is what are you looking for as there are numerous niche blogs out there - with that:
A good place I peruse is - The Trades Hub
I guess I can't forget to mention mine - The HTRC with a list of 20 on this page (2012) & 10 more on this one (2013)
For an architectural one from a guy that gets it and is worth a good laugh every now & then - Bob Borson's Life of an Architect
Second A Concord Carpenter & I would add My Fix it up Life to the mix along with One Project Closer (which unfortunately has gone inactive)
