Hi Brian

Long time, no speak. What I was primarily getting at was SEO for SEO's sake. I'm getting tired of seeing people spend 10 hours writing a single intro paragraph just to make sure it has the "perfect" keyword density - and yet it fails as a "perfect" introduction to website visitors.
You're definitely right in your statement that once you get a good userbase, you forget that SEO gave you your start. I will have to admit that I mod_rewrote DaniWeb for the SEO benefit. But I can't help but admit that it has usability aspects as well ... thread123.html is very easy to remember and type in, encouraging word of mouth marketing.
It's for this reason why I just despise the latest craze of keyword stuffing forum thread URLs for SEO benefit. I highly doubt that there is any benefit to naming a forum thread URL
is-seo-a-part-of-your-business-plan-t123.html instead of just
thread123.html. The only difference IMO is that the first is a huge hindrance to site usability and word of mouth marketing. It's wordy, long ... and is the 'a' included or is it 'your' business plan or 'my' plan? Users certainly won't remember! And you still need to include the numbers anyway to accomidate for multiple threads with the same pagetitle. Completely ridiculous and unnecessary!
Design your site with usability and accessibility in mind ... use descriptive titles to stir user interest, wrap an article's title in <h1> tags, description in <h2> tags, and body content in <p>, and that's all the keword density thinking you have to worry about.
