I feel your pain. I'm a very early user of the site (3 digit user id from when it was initially a closed beta) and used to answer questions regularly in my specific area of expertise. But the torrent of low quality questions from users who severely lack any fundamental knowledge in their subject area became too much. I gradually drifted away from participating and imparting my knowledge. I'm not going to spend time explaining the basics to users (who often show very little gratitude or appreciation) and cajoling them to provide other information that might help me solve their problems. It's a damned shame because the idea of SO is really good, but the site is overrun by vampires and I'm all out of stakes and garlic.
