FAQ: How do I setup Twitter feed?
How do I setup a Twitter Feed, I see it wants me to set up Twitter app keys and authorize my Twitter account?
the general issue of one of getting a Twitter feed into a web page, which I’ve always done via RSS. Apparently that’s no longer an option, as Twitter is moving from XML to JSON. I did find this wonderful web page with instructions on how to make an RSS feed from the JSON feed.
The process is probably too complicated for a casual user, however. That said, I followed the instructions to the letter and it works like a champ.
The idea here is that one must make a Twitter App to be able to get a Twitter feed, due to the api change from 1.0 to 1.1. I imagine WordPress.com simply has an app already encoded that does all that for the user.
You might look at other Plug-ins that are available for Twitter already installed in the VT Blog instance or find one and request that it be added.
