On the assumption that you're actually curious about why Ripple isn't really considered much around here, it has a lot to do with the centralization.  Whereas the "altcoin" family are all, to some degree, clones of bitcoin (yes, they vary the algorithms and the block rates and ceter, but the hallmark is a decentralized ledger kept on a P2P network), Ripple, as far as I understand it, is owned and operated by a single company which, while using some cryptography to secure transactions, doesn't have the main factors that people here find crucial.  The main one of those being decentralization---trustlessness.  The main idea thesis of Satoshi's white paper is how to create a trustless exchange system that doesn't rely on a third party.  People here find that crucial.  I hope this helps.
