(doc) less technical headline, more compact introduction

* FAQ: moving motivation from README.
* README: headline is more appealing to a non-technical public. Introduction now presents WebTorrent and ActivityPub.

+## Why did you create PeerTube?
+
+We can't build a FOSS video streaming alternative to YouTube, Dailymotion,
+Vimeo... with centralized software. One organization alone may not have
+enough money to pay for bandwidth and video storage of its servers.
+
+Our stance is that only a decentralized network of servers can provide an
+acceptable answer to technical issues (bandwidth, transcoding expenses, etc.)
+and social answers (need for a particular moderation policy, preserving
+content, etc.).
+
+While a paragraph is not enough to answer all these problems, PeerTube has
+very early prouded itself for using a contributory design, both for creating
+communities as federated nodes (as [Mastodon](https://joinmastodon.org/) for
+example), and for seeding videos (instances can seed each other's videos). But it's not
+enough because one video could become popular and overload the server. That is
+why we need to use a P2P protocol to limit the server load. Thanks to
+[WebTorrent](https://github.com/feross/webtorrent), we can use BitTorrent
+inside most modern web browsers, and users become seeds as the video gets
+more viewers.

+PeerTube is a free, decentralized and federated video platform developed as an alternative to other platforms that centralize our data and attention, such as YouTube, Dailymotion or Vimeo. :clapper: But one organization hosting PeerTube alone may not have enough money to pay for bandwidth and video storage of its servers, all servers of PeerTube are interoperable as a federated network, and non-PeerTube servers can be part of the larger Vidiverse (federated video network) by talking our implementation of ActivityPub. Video load is reduced thanks to P2P (BitTorrent) in the web browser via <a href="https://github.com/feross/webtorrent">WebTorrent</a>.

-:question: Motivation
-----------------------------------------------------------------
-
-We can't build a FOSS video streaming alternative to YouTube, Dailymotion,
-Vimeo... with centralized software. One organization alone may not have
-enough money to pay for bandwidth and video storage of its servers.
-
-So we need to have a decentralized network of servers seeding videos (as
-[Diaspora](https://github.com/diaspora/diaspora) for example).  But it's not
-enough because one video could become popular and overload the server.  That is 
-why we need to use a P2P protocol to limit the server load.  Thanks to
-[WebTorrent](https://github.com/feross/webtorrent), we can make BitTorrent inside the web browser, as of today.
