I'm a BIG blog reader. I can't stop reading blogs. Blogs helped me find this site (in particular Jeff's blog). However I've come to realize that all the blogs I read deal with one language.
Did you guess the language?
Well now I'm learning C and using GTK (The Gimp Tool Kit). I can't really find any bloggers who actually blog about C like Jeff, Eric, Jon, or Scott do about C#. I need the blogger to be active, and it'll help if he has a sense of humor.
I'm really sorry, but I've made the same search, and the result of my search was sad but expected. C# is a hot topic these days in development circles compared to C [*].
I'd love to be proven wrong, but there is simply nothing in the C world equivalent to the blogs you've mentioned.
[*] I am not criticizing C, It has been my bread and butter for the last 3.5 years, just stating the reality
C is not as hip as C# and friends. You will not find many blogs about it.
The only blog I can think of where I got some relevant C info is, There Is NO Box.
I think that the C equivalent of a blog is called a book. Step away from the internet browser :-)
You may want to keep an eye on this fellow named "Jibz" who recently started up: http://www.hardtoc.com/
I go back to the 90s with C. I'll write more if people will read.
That thing about books was explained to by a friend (jacox): "You can't grep a dead tree."
