No, absolutely. The problem with ISTQB Syllabus is that it does not really reflect modern approaches and methodologies (especially in agile environments). I attended ISTQB training recently myself and I must say that at least half of it was useless (problems that were mentioned do not exist in an agile team to which I belong).
But...
Although it does not say much about you as a tester it may be a value to your career. Depends on where you live (or where you will be seeking jobs in the future). In my area, the certificate is always mentioned as 'nice-to-have' in all job adverts.
From what I've heard the advanced-level exams are much more difficult and if I were you I would take at least one of them.
Now, I said the certificate is good for a career even if it doesn't give you much knowledge. So you may wonder - is there any training/certification that comes with some useful knowledge? Association For Software Testing provides online training. They are not (yet?) recognized by employers, but I heard they can change the way you look at testing. I am not sure if it's truthtrue or not (although people who told me about AST were definitely trustworthy), but I am going to take the training in September. Then I will share my thoughts here. ;)
