I agree high-quality writing is a solid skill, but I worry whether content-farm writing is a particularly plausible inroads into that. I suppose it can help improve writing skills from completely nonexistent up to the level of being able to string words together, but I'm not sure writing articles along the lines of what you find on eHow is going to help you land a more solid writing job, like technical documentation. In the worst case, it could count as worse than no experience to mention on your CV, since that kind of writing has a poor reputation.
Hopefully I'm wrong, but I think there are a lot of entry-level jobs that are sort of dead-end and don't really develop into a skill ladder, which is something to watch out for.
