I'm not a cheapskate but, blogger gives the user rights over the template and the css. Unfortunatley blogger sucks and isn't optimized, and the templates are hard to modify the only thing that's good is that google indexes them faster. Css doesen't harm the user that visits the site, and anybody can create. Editing css can be ok as long as the script has less then 50kb. There should also be a place for uploading images for the theme. Total size of theme images should not exceed 100kb. This would make wordpress more popular, having massive users coming in from blogger.
So wordpress, please let us create our own personalized themes for wordpress.com.
