a really small thing to fetch webpages main content and print it as markdown
basically its just readability-lxml and html2text glued together
pip install git+https://github.com/puhoy/readability_cli --user
readcli SOMEURL
from there, you could pipe the result through pygments and a pager, for example:
readcli https://github.com/puhoy/lspace | pygmentize -l md | less -R
or append website content to a file using vim:
:read !readcli https://some/url
