@ehBeth,
That may be, but in my experience both here and at other sites, few people actually do literal content searches. Years and years ago, there was a member here who would post anti-evolution BS without attribution. It was simplicity itself to do a literal text search to find his source. The sources were either anti-evolution, religious web sites, which could be challenged on the basis of an agenda; or they were legitimate, reviewed articles which had been "quote mined," meaning their content had been taken out of context to give an impression counter to the overall meaning of the article. That member would always disappear for a while, and even relatively sophisticated members here would ask me how i came up with those.
It's possible, of course, that people would be lead to eHow by literal text searches. However, i suspect that such a search technique is still relatively uncommon. Something which enhanced unique key words or phrases would be more useful to them.
