Depends on how seriously the subject is being treated, and the tone of the post: the vast majority of atheists on the internet are either militant proselytes or complete idiots or both, as one mostly gets "GOD sux, lol!" type posts in many different flavours, guises and combinations, but when you do get a plainly serious thinker with intent to describe his or her position non-confrontationally, it can be very interesting. Young men and women who post as atheists and take childish delight in calling theists "delusional" and thriving on their pet duality are never interesting, or deserved of being taken seriously.
If atheism brought you peace of mind and enriched your heart, it would be worth something. But if it serves you only as a tool of conflict and disharmony with your fellow human beings, you ought to take some time to reflect on yourself personally...
