There was a 2-minute advertisement on TV a few weeks back about a ladder. I did some quick spelunking and, as I suspected, the ladder is not very good according to many many people who have tried it. In theory it was a good idea, but part of me worries when I start to see very long advertisements for a product for the following reasons: I'd be paying for their advertising if I bought the product; if they have to market it so aggressively, then it can't be that good; I don't want something that's shoved down my throat (e.g. Microsoft Edge) and finally the testimonials are almost always biased, so they must be hiding something.
