Our open source digital signage software has two ways to view Tweets in a Presentation; the Twitter List and Twitter Branch Gadgets. Both of the Gadgets allow you to add Twitter queries to show the exact Tweets you want. We get asked a lot in our Forum about Tweets not showing up, how to look for very specific Tweets, etc, so I wanted to share some of the techniques we use when asked such questions.
First, you should check out the Twitter search operators. These operators are what you can plug into our Twitter Gadgets that define what shows up. The default search criteria for both Gadgets is @risevision, and this is going to show any Tweets referencing Rise Vision. You can change this to something like Windows OR Mac, the OR operator will show any Tweets for Windows or Mac or both. If you only want to see Tweets from a certain person, you can use from:homersimpson, and the from operator will make sure it only shows Tweets from that person.
Now sometimes you put everything in, but you still get the funny feeling that something is not showing up correctly. In this case, you should check out the Twitter Widgets, my particular favorite is the Search Widget. These Widgets are offered directly from Twitter themselves, so on top of making cool Gadgets that you can put into your Digital Signage Presentations, they are the perfect way to test if Twitter is delivering what it should be. Just enter your query, and hit "Test settings". The Twitter Widget on the right side will show you your results.
I hope you found this post helpful, and I look forward to any questions you may have in the Forum!
