Red Heart is actually a huge brand. It's mostly known for the "super saver" skeins where you can get a metric shitload of yarn for cheap, and if a supermarket, walmart, or Target has yarn, it will most likely be Red Heart. However, if you point out anywhere on Ravelry that you get what you pay for with yarn, a whole host of people who only use RH will descend upon you for daring to insult the yarn that their granny made their favorite blankie out of, and don't you know that some people can't AFFORD anything else, you horrible yarn snob.

Pointing out that you yourself use RHSS for certain projects will have no effect.

There's lots of talk about "yarn snobs" on Ravelry, but the wankiest people I've come across are ones that are loudest about how cheap their yarn is. It's baffling.
