I'm going to agree with AM on this one. Card Counting is so versitile that you should always be familiar with it as a base for AP. The more advanced techniques in blackjack are all opportunisitic. Be it shuffle tracking, ace sequencing, hole carding, steer card play or any varient of these methods, they all require so specific dealing weakness - with the dealing or shuffling proceduer.
If you intend to play very seriously, i would advise becoming familiar with these techniques and using them whenever you can, but they are not the be all and end all. For most regular players who just want to have an edge counting is still a very useful tool and even for those who want to play for more serious money you should never forget counting.
A good example of this is a venue i know of that offers nearly 90% on its 6D game (varying between 75-90% depending on the dealer and often massively shuffle to shuffle) that will happily see me playing a 1-25 bet spread and table hopping. This is a fantastic opportunity. Now i can also easily track the shuffles in this venue, with provide very powerful packet information and i do that any time a good opportunity arrises, but i would never laugh off the counting game when it also offers a very sweet fruit for the picking.
Anyway, back to the topic:
