Proposal: Create a page pymc.io which acts as a news feed for PyMC

The cards on the homepage? We thought about using cards on the homepage to highlight specific
news or resources. For now we started with an event, a blogpost and a talk because we felt they were interesting things to showcase, but the cards are completely manual in all aspects, we can choose the title, text, color and link at will (and for now only one is an internal link, the other two have external links).

In the future we might want to keep 3 cards (but update them to pymcon, major version and google summer of code) or we might want to add more cards either as a new column or as a carroussel (like the testimonials on the docs homepage) so that still only 3 are visible by default
