I've been following that advice since I first heard of Twitter
And as such I don't have to deal with spam from them (Or what passes for content on that site). I've never seen an advantage to Twitter over just subscribing to the RSS feeds of the websites I care about. It'd be useless for posting my view on anything anyway as I write in complete thoughts, so anything that I'd post to Twitter would be links to my personal blog, which has an RSS option already.
