I don't think RSS numbers are relevant anymore. Bloggers should definitely getting rid of them for good.

The problem is that many advertisers are seeing those number as a proof of quality and/or traffic of your site. For example BSA are adding RSS stats for each site on their marketplace.

But if feedburner continue to be a pure joke like it is now, many people, including myself, will simply get rid of their – once very cool – chicklet.
