I don't really care if some clown has edited the Wikipedia page on Atheism to say something that contradicts what I just said or not.
If you want to redefine the language, you should first change your name to Ayn Rand and then make sure you write a couple of really good novels to give your ideas some weight. I'm sorry if English is your second language, but the normal everyday definition of atheist is one who lacks faith in a god. Trying to redefine that to mean "one who is certain there is no god" is a religionist's trick to try to make atheists look more extremist than they actually are. If you suspect there might be a god, but you aren't certain enough to declare it as a faith then you are an atheist, one who lacks faith in a god, nothing more, nothing less.
Agnosticism has nothing to say about the existence of god. Agnosticism is simply the idea that some things, which may or may not include the existence of god, are beyond our knowledge. It is simply an admission the human knowledge has limits that we cannot cross. Many agnostics are atheists, many atheists are agnostic, but there are also "Strong" atheists that are not agnostic, and religious agnostics that are not atheists. The two ideas are somewhat related, but they are neither the same, nor mutually exclusive. It's that simple.
