/me not a Twitter user Are Twitter upvotes really a useful guide to article quality? I note that the searches the MarketRank people have reported on are all concerned with startups and software. I wonder how it performs on e.g. political analysis, recipes, DIY, living on a budget and so on. I find it particularly hard to find product reviews that aren't rather shallow re-hashes of marketing material; a product review that points up the deficiencies of a product is a rare animal indeed.
