So when i post a tweet with a hashtag in it, it shows on my timeline but doesn't appear on the hashtag-TL. like why not? apparently other people can see them though, because sometimes these hashtag-tweets will faved by someone. so what's going on? help!
Well, that annoying invisible-tweets problem seems to have been resolved somehow. and rather mysteriously too, i must say ... although i suspect that sending a report to twitter-support may have had something to do with it ... wut? you think so too? idk
If, under the Notifications panel on the Settings page, you had changed the default setting to either "all @ replies" or "no @ replies," your setting has been reset back to the default: Replies sent from people you follow to people you don’t won’t appear in your public timeline.
