Well, I don't know any off hand examples at the moment. I was typing something, but it only used about two howevers. It's tons of techno-babble about Fedora Core 5 for Linux.

I figured using 'however' more than three times within a page was very bad writing. That's why I've been switching between yets and buts. However, the reader would eventually catch on to my writing style. Afterwards, it would be silly to use such thing. Yet the psychology of a reader does not watch a blank television screen, nor does he or she like a monotonous and elongating paper of dribble stated in "if--then" statements and "howevers". This is why I've been trying to alternate between usages. However, I haven't been able to fashion my own style to such a perfect state. A state in which "howevers" are slowly eliminated through time (I apologize for inproper quoation-mark usage).
Sometimes I feel as though I use 'however' in every paragraph.
