A number of iOS 7 users have reported problems sending and receiving using iMessage (not that it's the first time), and tonight Apple has responded. The Wall Street Journal has a statement from the company claiming the issue affects "a fraction of a percent" of its iMessage users, and says it will be fixed in a future software update. TechCrunch points out a support document that may provide temporary relief to those experiencing the issue, otherwise users may need to fall back to one of the many, many, many other messaging services out there (but not BBM, yet, and Google Hangouts had its own issue recently) to make sure those messages are getting through.
