For 183: Umm, i would prefer on public_timeline, firehose, Data mining and status/show? I collect the timezones (as you know for TwitterTrend) and as of now I have to collect the UserID then get the user/show timeline only for the "time zone" field, which hurts my end and gives you more load.
For 180: The field just doesn't show up in data mining and public_timeline? It works fine in status/show and user_timeline. Is this on purpose? Thanks so much! -James Hartig :) http://twittertrend.net
