Is "What's new?" button important? Would be nice if we could get rid of it as well. 😄

It looks much better @yathomasi! 🙏 It's still cut off, but you can definitely see more.

@skshetry The "What's new" button is important it gets people to the latest on the blog, though we need more regular content as discussed this morning.

One thing I don't understand is why the page leads with DVCx right now. I think ultimately this makes sense at the release, but right now it's kind of odd and feels sell-y for the dvc.org website (even though it shows the open-source version, I'm speaking about the driving to waitlist part). It would make more sense to include it at the end after what was there before. But I guess we are not talking about much time in this state theoretically. 🤞
