Full RSS feeds reduce activity on a blog?

Interesting question. I dislike the provision of full posts in RSS. It’s not about ad revenue (I don’t make money from my blog) or anything else except for my belief that the web is perfectly adequate and — indeed — superior to RSS feeds for human communication; RSS feeds on the other hand are excellent for notifications of new content (the pseudo-push aspect previously missing from the Web) and automatic dissemination of content to multiple sites/aggregators (even though I have my qualms about this too; there should be a better standard for this). Yet, CogDaily’s experiment is flawed. The time-series is too short, the information does not cover all aspects of ‘activity’ of a blog and — by their own admission — the samples are not representative (there was reduced content publication). While I (intuitively) agree with the statement the data provided by CogDaily do not seem to support it.
