Lately I've been noticing that when I post a tweet, everything appears instantly to users who are logged into their twitter accounts but if I clear my cache/cookies and visit my own site I don't see my latest tweet. Sometimes for several hours or days.
If I email their support, they say it looks normal on their end and then magically it's working. Until next time, at least.
Pretty frustrating because I know a lot of people have twitter pages bookmarked but don't actually have an account of their own, so they're "following me" but not really, and don't know I've sent an update. Does anyone else experience this?
