Hi Spode, Thanks for your questions, i've answered them inline.

The new IDs will be greater than the old ones and there is likely to be a gap between the old and new. I'm not sure what you mean by being incompatible though - an ID is a unique identifier for an object and the new IDs will continue to be unique identifiers. > I have a database of several million tweets that JournoTwit users use. > I don't want to have to start differentiating between two ID types and/ > or having to completely clear the database out. You won't have to clear your database out or change the the datatype. The new status IDs are still 64bit integers, with newer Tweets having numerically higher IDs. > What I haven't seen amongst any of this documentation - is an example > of the new status ids in comparison to the old?

The new status IDs apply to Tweets, ReTweets and Mentions (so basically anything that can show up in the home timeline). The code that generates the IDs has been shared and you can read more about Snowflake from our engineering team on their blog. http://bit.ly/announcing-snowflake Hope that answers your questions, Matt -- Matt Harris Developer Advocate, Twitter http://twitter.com/themattharris -- 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?hl=en
