There is a tradition of philosophy with value.

Many famous and modern philosophers are distractions from this. The same was true in the past. Each generation, most philosophers did not carry on the important, mainstream (in hindsight) tradition.

If you can't tell which is which, to me that suggests you could learn something by studying philosophy. Once you do understand what's what, then you can read exclusively good philosophy. For example, you'd know to ignore Wittgenstein, as the future will do. But the worthlessness of some philosophers does not stop people like William Godwin or Xenophanes from having valuable things to say (and the more recent philosophers who are carrying on *their* tradition).
