(Continued) Repeating can be annoying. For an example, a popular post on the #PumpIO network can appear in your stream dozens of times. But that is mostly because it isn't implemented well. On any network (including this one) a repeat should merely bring the post to the top if you've already received it (and add something telling you which people have repeated it).
