Is crowdsourcing still relevant in 2019?

I'm working on a project that I would either need to take a long time populating the site with data, hire a copywriter or get some crowdsourcing. I'm wondering if crowdsourcing is still a relevant these days.

I think it depends on the nature of your project.

If you're looking to offload manual data entry, then you might want to look at Amazon Mechanical Turk. It's not precisely "crowdsourcing" because people who perform Turks get compensation. I've used it for personal projects, and the process works pretty well. You'll probably have to sanitize data afterward, but it's much quicker than the alternatives.

Again, this all depends on the nature of your issue. If you would like to talk about this further, then feel free to ping me directly on Telegram.
