I can't tell if you mean 'because I find it difficult too', or if you mean 'because it means I have less/easier competition'. Of course, this could have been your intention all along, but if it wasn't could you clarify?
Because I find it difficult too. :) Been using CSS for 7 years and still have some trouble with it, compared to typical programming which tends to be quite easy.
Cool! I definitely have trouble using CSS, I depend heavily on CSS frameworks & libraries to lay out anything remotely complex.
I use it a bit, but my focus is on the back end, so I never seem to get to the stage where I really understand it. Especially the nesting.
