To float or not to float

This should actually be titled "don't edit HTML in a browser."  I had a nice long post about using floats in HTML and the learning curve, along with lots of links.  When I viewed it in my web log, the page layout was all screwed up.  I tried to correct it by editing the HTML in Visual Studio .NET... cut, copy, paste into the browser, and update.  Close down Visual Studio .NET and noticed that I copied the wrong post....

Grrrr...
