WEB: Home page content for the new website
In #28014 we added a first draft of the new pandas website. It can be seen here:
https://datapythonista.github.io/pandas-web/ (will be at https://dev.pandas.io when #28497 is merged).

Things that are already in the home page, or that could be added:

- [X] Short sentence to summarize what pandas is about
- [X] Links to the main pages / section (feedback on things to add/remove/change welcome)
- [X] List of companies supporting pandas (do we need to formalize the criteria to be there?)
- [X] Info and links to the last version (download, docs...)
- [X] Follow us on twitter
- [X] Wes book
- [X] Links to previous versions
- [ ] Project highlights (See the home of Jupyter, Dask, Django or Spark for reference). How do we want it? What exact highlights do we want to list?
- [ ] Success stories. We have some in the current website (https://pandas.pydata.org/#what-do-our-users-have-to-say) but in my opinion we could do much better. Like some known faces/companies. I can ask one from the team of the black hole image for example.
- [ ] Summary of the ecosystem page. Like the basics, mentioning matplotlib for plotting, numpy for array computing, Jupyter as an interface, Dask for distributed...
- [ ] Anything else?
