I do. That's been around for quite some time and it can differ whether you are using the website or a client. If a client, it could be due to Twitter throttling API calls to avert a meltdown. If via their website, nearly the same thing, except they do have a hard-limit built-in now. When I began on Twitter, we could have high-velocity conversations about things. These days, we really can't without someone winding up in what I've termed "Twitter Jail." Twitter might also say this is to prevent mass spamming. But I doubt that. The spammers are still there.
