Let me start off by saying that I am a huge fan of WordPress. I love it from the bottom of my heart.
Now, on to the point:
I have been looking around and discovered that there are several blog(ish) sites that allow extensive customization of the blog's layout and presentation FOR FREE. Both the ones mentioned above even offer HTML customization.
I know that the price to pay for WordPress CSS customization is a small one, but really, I am thinking about switching to another service (like Tumblr or Blogger). At the end of the day, both core services do the same things, but one lets me do more for free, while one lets me do less.
I am suggesting that the WordPress team make the CSS editing feature free. This will place it on par with other big name blogs, plus you get the great WordPress service. Because to a shopper, at first glance, it's just going to look like this service is stingy with its features, while another is not. Most people aren't going to care about WordPress' great track-record or elegant design. They are going to care about features, and make their decisions based on that.
We have all seen the companies that continue to insist on charging for things that other companies offer for free--they die. Almost every time. It's the natural order of progress: things that were once a novelty become common-place, making way for new novelties.
I do think that there are some things that WordPress can validly charge for; I just don't think that CSS is one of them any longer. Think of some really killer features to charge for, not something the other guys are offering for free.
Long live WordPress.
