Of course, its solid. :) just make sure you use a hybrid model with js. Ex: if you want to just show user reputation, use steemjs on client side. (Browser) It feels much faster since it doesnt block the webserver process and response times. (doing a steemd call at backend blocks the server process).
A hybrid model with steemjs (on client side) and python for background (ex: custom apis of the dapps) works well.
