Promote your members
Several chambers of commerce use Twitter to announce when local businesses join. Below is an example from the Stillwater OK Chamber. In this example, they are also providing the member's address and a link to their website. You might also consider linking to a Google Map of their location or to that member's listing on your own website. (You can use URL shortening services to fit within the 140 character limit)

Another way to promote your members is to announce when they receive local press coverage or awards. The Clovis CA Chamber recently posted the item below to congratulate a member on being featured in a local publication, with a link to the article.

Connect your local businesses on Twitter
By using some of the tools I mentioned in this post, you can quickly find people and businesses in your area that are using Twitter. Once you've found them, why not let your followers know, too? The Asheville NC Chamber shared two local businesses and asked for others as well. This can be a great way to develop your community of Twitter followers.

Promote Ribbon Cuttings
Holding ribbon cuttings is still a big part of business for many communities. If your chamber does them, why not use Twitter to promote them? The Greenville SC Chamber does this. One thing I might recommend is to include a Google Map link to the location of the ribbon cutting.

Note: Try to use your chamber's name when ever possible. Using "Stillwater Chamber" or "Asheville Chamber" will help your tweets be found in search. You do use Twitter Search, don't you? As you might imagine, a search for "chamber" returns many more results than one for "Greenville Chamber." (Including some for chamber orchestras, gun chambers, etc.)
And Twitter is tweaking the SEO value of their pages, so using your name may help your chamber be found in more Google searches. Note that the Clovis Chamber used their Twitter name in the post above, "@ClovisChamber," which is another way of including your organization's name in the tweet.
How are you using Twitter to promote your members and your community? Please share your ideas in the comments below and include links to your tweets if you can.

I hope that everyone who uses TweetDeck always have a column for the search word "Chamber." I'm learning a lot about ways to use Twitter from other organizations (plus a lot about orchestras, barometrics, and guns, ha ha). We should probably have a regular schedule of announcing new members and linking to their websites. Thanks for the ideas Curt!

We have been trying to mention member businesses in tweeks but now that I really have my staff on board with twitter this will help us establish some routines. Our tweets are displayed on our new website, so this is perfect timing. Always enjoy your posts!

This is a really great article, and I will be thinking about this as I consider putting together some workshops for the Chamber that I just joined.

Great post! This is such an easy thing to do and really a great benefit to members. I frequently come across news about members--articles about them in local newspapers, videos they've made on YouTube, etc--this would be a great way to recognize them and make them feel appreciated. It would also be a great thing to offer members--send us the link to your blog or podcast and we'll tweet it.
