While I agree that the proliferation of subscription based consumer product services looks crazy, I think this post includes too many assumptions about how and why VC's are funding consumer startups.

You also seem to have a fairly negative attitude towards the teams behind these startups but I can't seem to see why this is justified.

Far from being without product innovation or branding, dollarshaveclub.com are changing the way we purchase razors and the price we pay. That video is their brand statement.

The fact that dollarshaveclub.com hasn't released a new product since receiving funding, or had another big viral video, doesn't mean all that much in itself. Perhaps they're selling so many razors that they're still fulfilling that market. Or perhaps they're working on a new launch with a longer product cycle.
