Check out SnapTweet. Another Twitter photo-sharing service. This time via Flickr.

Create an account on SnapTweet using your Twitter credentials and provide your Flickr username. Then you can fire off a direct message to SnapTweet on Twitter with the photo title and it will pull your last uploaded Flickr photo.

At first blush, Twitpic appears to be another service that adds file-sharing functionality to the Twitter experience. But Twitpic is special, because it focuses on sharing phots.

Use Twitpic to upload your latest photo to Twitter via the Web or from your phone. Twitpic saves the shot and sends the link to your Twitter followers.

Twitpic also offers an API for extending its functionality.

Want to share files via Twitter? Twit+ may be for you.

Designed to replicate that Pownce functionality that everyone loves, Twit+ allows you to “twitter with pictures or video and also privately send files to your twitter friends.”

Ever curious about who else in your hometown is using Twitter? Or maybe you’re interested in seeing the Twitter stream for a town you’re going to visit.

Twitterwhere is for you.

Using its simple search and location selections, you can have Twitterwhere an RSS feed of all the tweets from a particular geographic region, based on the location settings in user profiles.

Tired of missing Twitter replies? Twitter Reply Sniffer may be for you.

Designed by Justin Kistner, the original Twitter Reply Sniffer runs the public feed through Yahoo Pipes, allowing you to easily extract those replies that either sailed by too quickly or failed to make it to you at all. It was based on the Terraminds search of the Twitter public feed.

In a new version of Twitter Reply Sniffer, Dawn Foster has switched to TweetScan for the base feed, due to recent reliability issues with Terraminds.

Ever wished you had access to Pownce-like file sharing on Twitter? Well, now you do.

Try Twittershare. It’s currently available as either a Mac OSX widget or through a Web interface. And it allows you to upload a file (under 10M), generate a short URL pointing to the file, and send it to your Twitter folks.

Just like that.

What about the feedback on the tool? Here’s what some reviewers are saying:

ReadWriteWeb says, “When you’re perusing the list of the most popular Twitter clients, you won’t find others that support file transfers this large. I’ll put this one in my shortlist of handy apps to remember.”

Download Squad says, “So any time you want to send a document, photo, or song to your Twitter followers, you can just fire up Twittershare and upload your file. There’s a size limit of 10MB per file.”

P2P Blog says, “The only feature that is still missing to catch up with Pownce is the capability to send files to select groups of users - but Twittershare is definitely a nice start for hardcore Twitter users that want to share a file every now and then.”

A Windows app is in the works, possibly via Adobe AIR.

Have you ever created a Twitter entity for a blog or an organization? Like tweetness for instance? Don’t be shy, we all have. And that’s why I’m glad to see Tweetpeek.

Tweetpeek allows anyone to easily create a widget or a page, based on the Twitter with_friends feed for that entity. In Portland, we call them “Pulse of…(whatever).” Pulse of Portland. Pulse of Open Source Software. Pulse of you-name-it.

Now, you can call them whatever you want. And build them, just like that.
