The internet gurus say that if you're frequently changing the layout and design of your webpage, it's because the design isn't very good and that's why you're never satisfied.
And while this is likely true, it's not the only reason the layout and design of this webpage are always changing.
The reason is that I like to play with them and I can, so I do. It's fun and it's one way of learning. Granted, it's a slow and pathetic learning curve and there is no expert instructor to actually teach me anything. But as one fiddles around and tries this, that and the other thing, one picks up skills and tips. And that's a good thing.
