Pinterest is still active, and you can drive traffic from it. There are some helpful threads in the IM Journey section that share lots of details about people's successes and challenges over the past year.
When it comes to Pinterest, you need to be ready to manage multiple accounts, take things slow, and automate what you can. If you post about 6-12 images every day and have the patience to wait for around 5-7 months, you'll get a good number of impressions on your pins. By following best practices for pin design, you can get solid (not amazing, but solid) numbers of clicks to your website.
Using full or some semi-automation is essential to stay sane.
