[twitter-dev] Questions on user_timeline entities

[Sud]

Can someone answer these?

   1. *urls:* Are they expanded?
   2. *hashtag:* Is #thisahashtag? I think so.
   3. *user_mentions: *
      - Is @replyto a mention? So would "@replyto @abc" imply two mentions
      or just @abc?
      - What about this Tweet: "RT @abc blah blah @abc_mention blah
      blah (nice, cc @my_mention)"
      - Is screen_name the screen_name at the time of Tweet creation or at
      the time of Tweet access? (this applies in general)

Thanks,
Sud
