Help! My blog looks awful

And I swear I have not done anything! But apparently it is something Wordpress has done:

We’ve gone through great lengths to make this as painless as possible for theme authors.

Thank you!

You don’t need to know anything about Subversion (our back end magic takes care of all that for you), just login with your WordPress.org username and password and go to the upload page.

Magic, so how about sending Harry Potter?

From there you upload your regular theme zip file and we take care of the rest.
Once you upload your new theme we do a few automated checks for some of the requirements for each theme. If we find one that you missed we’ll provide you an error and description of what needs to be fixed. When a theme upload has been accepted we’ll send you an email and put it in the queue to be reviewed, to make sure we didn’t miss anything. After the theme has been approved you’ll get another email letting you know that the theme is now live.
That catches you up to where we’re at today.

But I liked the way my blog looked like. I did not want any change. I am a conservative!

When you finish that theme you’ve been slaving over, upload it to the new directory and let us know what you think. Since so much has changed since the old theme directory we’re starting fresh from zero. If you’ve got specific questions or suggestions contact us and we’ll do our best to get them answered.

Why change a winning horse?
