Yes, the only drawback is that its highly competitive. I haven't had much luck with landing a gig lately, and there are often 20-40 people putting proposals on a single project. It's frustrating that writers from other countries often underbid the price.
If anyone knows of a place where writers make good $$, pass along the information, please! But if you love writing (like I do), then getting paid any amount is just a bonus to doing what you love.
