runnervertex
Glad I gave this fifteen minutes rather than the usual three minute skim, and a look at runnervertex earned the same investment, time spent on quality content is rarely wasted but the reverse is also true and learning which sites deserve which kind of attention is part of being a careful online reader.
executeprogress
The use of plain language without dumbing down the topic was really well done, and a look at executeprogress continued in that same accessible style, this is something many technical writers fail at because they either confuse their readers or condescend to them but here neither problem appears at all which is impressive really.
