Twitter Implements Threaded Comments, Sort Of
By Jesse Stay of Stay N' Alive (Identi.ca/FriendFeed)
Today Twitter made a quiet announcement on their developer mailing list that could have profound implications. On the mailing list, Alex Payne, a leading developer at Twitter gave the following announcement:
What does this mean? Essentially now any Twitter client can now associate another post as a reply to another existing post. This means that Twhirl or TweetDeck can allow a user to post a normal status update, and provide a "+" sign underneath (or "@" similar to the Twhirl FriendFeed client), and a new post can be appended as a reply to the previous post."I'm happy to announce a minor change to the API that should have a major impact on the Twitter community. The /statuses/update method now takes an optional parameter: in_reply_to_status_id. As you might guess, this allows API clients to specify which status a status to be posted is in reply to, rather than our system assuming that it's in reply to the last message posted by the user specified by "@username". "
What's very interesting though is that Twitter is not requiring "in_reply_to_status_id" requests to have an "@" symbol in them. Therefore, this could very well mean the death of "@'s" on Twitter as more and more clients begin to fully implement the API call. Twitter seems to be breaching FriendFeed territory on this one, if they could just start allowing better aggregation.
I expect to fully see new implementations of this feature very soon - the request is quite simple, and would just take some simple UI enhancements. Twhirl I know has these built in already to their FriendFeed client - they would just need to utilize the same code and they would have it in the Twitter client. Now the question becomes, will Twitter's API limits allow this feature to work? It will be interesting to watch.

Adobe's AIR platform is seeing a rise in applications designed to bring Web activity to your desktop. From
Posty, from a single black square window, lets you post updates to six different services, including Twitter, Jaiku, Pownce,
As with other AIR apps, you can take appropriate actions per service. For FriendFeed, you can like or make comments. On Identi.ca, you can reply or go directly to the update. And on Twitter, you can reply, mark as a favorite, or open the note in your Web browser. This wasn't always available, as in the very first release of Posty earlier this month, you couldn't see your friends' updates, only your own and public timelines. After I traded e-mail with Cesare a couple weeks ago, he was quick to respond with a new version incorporating the update.
On July 4th, I had the opportunity 



Unlike some applications, whose preferred mode is single column, getting me only my Twitter stream, TweetDeck is actually very well built for being used in full-screen mode, of course, running in the background. Now, with one glance, I can see all updates, see all replies, and keep my eye out for keywords. And rather than force me to go out to Summize to search a keyword, TweetDeck has integrated Summize's search capability and also its ability to find replies, although, in version 0.15 beta, released just this morning, Twitter replies now have precedence, should there be duplicates.
In the bottom right corner, TweetDeck reports: "Twitter Status: Pretty much ok" or "Twitter Status: Rate limit exceeded" when there's a problem. It also provides a status as to when it was last updated, how many tweets were received, and when the next update is expected, polling every couple minutes.
