To take it back to Jimmy M's original point-
Wasn't about TAB or not, was about an attitude towards people who could read and regarded it as an important aspect in their bass playing.
There is no universal right or wrong, only what is applicable to an individual and their own needs, ambitions and aspirations.
I happen to believe that reading is a valuable skill which can offer much to any musician- on the other hand I can't slap- never seen the need for it, never learned it, never practiced it - it's not important to me in the way I play my bass and get enjoyment from it.
In another environment, for example, if I aspired to earn a living from playing my bass, I would be seriously disadvantaged in that ambition by an inability to do this.
If your toolbox of skills satisfies your needs then you are in a good ( although some would suggest stagnant) place- if not, do something about it.
However, please don't slag off other peoples experiences and viewpoints with generalizations, which if I read it correctly, is the point of the original post from Jimmy M -I don't care if you read SN or TAB, play from chord charts, listen and learn or extract the notes from the ether of the universe as long as it sounds good- and more importantly, your audience doesnt care either- but dont slag off the way others do it or attempt to denigrate others views and experiences because they are not your own, from a sense of insecurity or inverted snobbery, or indeed any other reason, there lies a dangerous path....IMHO, YMMV, no animals were harmed in the making of this post, etc etc

(Apologies for the long post/rant, but IMHO, this is all getting a bit off the point)
