Steemit is a great place to start yor portfolio I agree. I actually was using Wordpress as well I've been blogging since undergrad days. I always ask my self the same questions! What are my interests and ever since I went to school for writing not only is it a hobby or fun but almost like an addiction. I always have to be writing somewhere whether it be a blog or in a notebook. Steemits platform gives us the opportunity to meet people that share similar interests :) thank you for your post !
