Twitter’s Audacious Plan to Infiltrate All Your Apps Twitter's Fabric does lots of very pretty things, and the people who write mobile apps are going to eat it up. Which, OK, that’s nice. But the bigger story is what Fabric represents. Because it isn’t just a tool for developers any more than Greek horses were meant to beautify Troy. Fabric is the foundation for Twitter to transform a business based purely on a single product—tweets!—into a diversified service aimed at every person and company that makes mobile apps. That, in turn, would affect every person who uses mobile apps. In other words, everyone. So IF Twitter reasonably succeeds in this, it could end up giving a good run for their money to Google (already facing growth issues in ads) and Facebook (which seems to have better execution/understanding than earlier).
