hi, I'm the creator of swytch. Actually I don't agree that the interface looks similar - i assume you're referring to the screenshots they released? Besides the colours what else is similar and just how would you expect a news feed to look? What you see on my site is typical of what you might see on any site designed by a programmer. No frills and functional.
As for privacy, we're not the only ones working on addressing the privacy issue, that doesn't make us a clone.
