I just read a few lines from Canetti‘s autobiography that did catch my attention because they have somehow to do with blogging as a way to share knowledge:
… zum Wissen gehört, dass es sich zeigen will und sich mit einer blossen verborgenen Existenz nicht begnügt …
and next
Das Wissen, das in Erscheinung tritt, indem es sich anderen mitteilt, ist das gute Wissen, wohl sucht es Beachtung, aber es wendet sich gegen niemanden.
The quotes as I understand them, say that whenever you have knowledge on something, the best you can do is to share it with someone. Keeping it for yourself is bad knowledge. Sharing is asking for attention, but is not aiming against anyone.
That looks like some kind of motto for my blog: the good knowledge.
