Bitcoin is a victim of its own success. Double-whammy: the exchange rate is now higher and people are executing more transactions. If your transaction wants to compete with the limited block space for each transaction, you have to increase your fee (or your transaction will be queued until activity is low enough that no one else's fees outbid yours). The community is considering several approaches to mitigate the problem and the different approaches have exposed the distinct underlying motivations of miners, merchants, exchanges and customers/users.
