I have just upgrade thematic to the latest version. Thematic is the wordpress theme framework that i use on this blog currently, i blog about it during V9 release and V9 part 2
I am happy with their latest release which provide custom hooks and filter , i have just recode some of the part of my child theme, all the google ads on my them now is embeded through the function.php, which mean any upgrade of the thematic in future, i can just overwrite it and without rewrite the the code.
I think in future maybe all the famous theme will work in this direction ? which allow easy customize and easy for upgrade. Anyway i tweak some of the css also , font size increase by 1px , let me know if you think the font size is too big ? or too small.
