the data science blog 
Very good blog! Do you have any tips for aspiring writers?
I’m planning to start my own website soon but
I’m a little lost on everything. Would you recommend starting with a
free platform like WordPress or go for a paid option? There are so many choices out there that I’m totally overwhelmed
.. Any recommendations? Thank you!
