Dwigger is a voting and threaded conversation tool for Twitter. The main aim of the team behind Dwigger was to create a tool with which you can “digg” (vote) someone’s Twitter comment or get votes for your own comment. Dwigger supplements Twitter by putting „Tweets” (Twitter messages) into threaded conversations with vote buttons. “We love Twitter - but the social interactions sometimes don't work very well. We want to make Twitter more interesting for people to use,” – the team says.

Dwigger members vote on submitted Tweets. If a Tweet receives enough votes, it will receive extended attention from the world. The highest voted Tweets of the week are posted in the „Top this Week” sidebar.

If you are creating a new post directly on Dwigger, you have the option to post additional information that will extend your post (longer than the standard 140 characters of a Twitter post). This expanded post may contain more text, images, embedded videos or other content. Although the extra information isn't included in the Tweet at Twitter, it will be displayed as a link from your Twitter Tweet back to your original Dwigger post. If your thread has extra info you can modify it, but the main contents of your Tweet cannot be modified because Twitter does not allow it. Comment Tweets can not be modified for the same reason.

On Dwigger, the threaded comments are Tweets. On Twitter your Dwigger comment will be posted as a reply Tweet. If the comment you are posting is longer than the 140 character limit on Twitter, only the first part of your comment will be displayed on Twitter followed by a link back to your full comment at Dwigger.

There is a “Hit List” which is a real-time keyword search for what's being posted at Twitter „right now.” You can post Tweets to Dwigger that you find on the Hit List by clicking the „submit to Dwigger” link in the Hit List results.

When you first join Dwigger, all the users you follow at Twitter are added to your followers here (except for "protected" users). From that point on, any time you add or remove a follow on Dwigger, Twitter will be updated accordingly. If you add new follows at Twitter, you can click the "import" link on your Dwigger profile to import from Twitter any follows you haven't already added on Dwigger.

You can use Dwigger by logging in Dwigger using your Twitter credentials. Then use one of the two ways to put a Tweet on Dwigger: Either create a brand new Tweet right here on Dwigger, or you can paste the URL of any Tweet that is already posted at Twitter; it doesn't have to be your Tweet. If you find an interesting Tweet of any public Twitter user, you can post it to Dwigger. Every post you submit (with the exception of blog posts) also updates your status at Twitter. You can even start a Dwigger thread via SMS (text message).
