Howdy, Twitter fans. Looks like it's Tuesday again already, and it's time for another installment of the best Twitter news and app of. Let's get to it!

The biggest news this week is an upcoming improvement to Twitter's Places feature. No, it's not a head-to-head Foursquare or Facebook Places competitor (yet), but it will allow businesses to claim their physical locations. If you haven't seen a Places page yet, take a look at the page for Twitter HQ. Note that these pages show all recent tweets sent from that location, which could be totally useful to a business.

Twitter told Mashable that "Claiming Twitter Places is not available at this time. We're experimenting with a variety features. Allowing businesses to claim a Place is a natural thing to consider for the future." This could mean any number of things, from a very basic tool for business to advertise specials and deals on their Twitter Places pages to a full-on check-in system. Twitter will need to find an incentive for business to claim pages, and an incentive for users to add their locations to tweets ... could Twitter Deals be around the corner (they worked so well the first time around as Early Bird)?

'Blackbird Pie' Makes Embedding Tweets a Snap (Now With WordPress Integration)

Blackbird Pie is a little-known Twitter feature that allows you to embed a tweet in a webpage, with formatting, working links and even your Twitter background completely intact. It's going to be a lot better known soon, though, because WordPress is integrating it with all WordPress.com blogs. In a post or comment on WordPress.com, you can activate Blackbird Pie by pasting the address of any tweet on its own line -- the rest is automagically done for you. If you want Blackbird Pie on your self-hosted Wordpress blog, you can install the plugin.

Twitter For Adults

Over at Lifehacker, they've republished web luminary Derek Powazek's brilliant post on Twitter curation, Twitter for Adults. I'm not going to copy-paste the whole thing into my column, but I do consider it highly recommended reading. Derek has some great ideas about how to get the most out of Twitter, including turning off new follower emails and turning off retweets for people who overuse that feature. He also recommends taking serious and nuanced topics off of Twitter and addressing them in a longer form. "Twitter is like shouting over the band in a bar," he writes, "You can do it, but you have to keep it short."

Visualize Your Twitter Followers' Locations With MapMyFollowers

If you want to know how global your Twitter following is, MapMyFollowers is a quick way to find out. It displays your followers as pins on a world map, with up to 1000 followers per map. You can hover over each pin to get a follower name, and click to see details. It also gives you a cloud of the common terms your followers include in their bios. (I never knew so many husbands, fathers and designers followed me!) It's a simple idea, but it's a very interesting way to look at your Twitter flock.

Weet Desktop App Signups Now Open For Users of Weet iPhone App

If you're using the Weet Twitter client on iPhone -- and you definitely should be, if you miss the way Tweetie used to be before it became Twitter for iPhone -- you can now sign up to beta test the desktop version of Weet. The option appears right under the accounts menu on the front page of your Weet iPhone app. If you're interested in the desktop app, now is the time to shell out 99 cents for Weet for iPhone.
