I've also been facing this issue for quite a long time. I've told myself that this can't be a problem with the API (since nobody else is complaining) but I can't see what is wrong on our end. For example, I have the following status that was retweeted a few times:
http://twitter.com/#!/anilchawla/status/14437959797313536 This is the request URL that is generated when I request my mentions using count=200, include_rts=true, and since_id = 13978625736970241 (OAuth tokens omitted): https://api.twitter.com/1/statuses/mentions.json?count=200&include_rts=1&since_id=1.397862573697E%2B16 The four mentions of the above status are not present in the response even though those retweets and the original status have an ID greater than since_id. Omitting "count" and "since_id" does not make a difference. As a work-around, we have to pull both statuses/mentions and statuses/retweets_of_me and merge them together. It's hard to believe that everyone else has been doing the same and ignoring this API parameter. Any idea what the issue is? -Anil -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
