For months I had been periodically tweeting questions at various public figures, and when I thought they didn't answer, I removed the tweet.
Now I've just discovered "Interactions" under "@Connect" on the Twitter site, and realised that they were replying all along, but I have no idea what my original questions were because I deleted them. (Which is really frustrating.)
What I don't understand is how this happened in the first place.
Why don't I get a notification informing me when someone has @replied to me? What am I missing here?
