Its time to tag your favorite commenters on PS. If possible, add a brief note explaining why you value or hold in high regards the comments of those you choose.
My favorites are @Rumraket, @Mercer and @AllenWitmerMiller, @John_Harshman and @sfmatheson
Rum’s comments on science or atheism are generally well articulated and relatively easy to understand. His command of basic concepts in molecular biology and evolutionary theory are highly commendable: I once thought he was into active molecular biology research based on his comments at Larry Moran’s Sandwalk blog, until he updated me with accurate details. Overall, he is a fun person to dialogue with and there are nuggets of knowledge one gets from conversing with him.
Mercer’s comments are typically straight to the point especially in discourse about science. Reading his comments allows you to keep track of whether the important claims made by someone have been scrutinized using the best data available. His comments focus on the most crucial demand in any scientific conversation, which is good evidence. Needless to say, his wealth of experience from decades of molecular biology research clearly shows in his comments related to it.
I have three other favorites, but these two reviews should suffice. Let’s know yours.
PS: if you have favorite lurkers as well, include them in your list.
You didn’t make my day or anything 
actually I’m sitting outside and the sun is shining a bit through the clouds, even though it was supposed to be a rainy day and my boys are getting to watch an excavator next door. Doesn’t get much better day than this.
. Thank you!
