Well folks it looks like the days of advertising free tweeting may finally be coming to an end. The rumors are flying around regarding the ad platform that Twitter has in the works and is testing. Everyone is “atwitter” with this change and for good reason. Of course, until there is more than what has already been released by Twitter itself any ideas / thoughts about what Twitter ads might look like are for the imagination.

MediaPost reports on how this whole thing really started to bubble to the surface.

Twitter plans to launch an advertising platform in about a month, according to Seth Goldstein. The chief executive officer and co-founder of socialmedia.com led a panel Monday focused on the next wave of interactive advertising at the IAB Annual Leadership Meeting 2010 in Carlsbad, Calif., that shed light on Twitter’s strategy.

Declining to confirm exactly when Twitter would release the platform, Anamitra Banerji, head of product management and monetization at Twitter, told MediaPost following the panel that “we are working on an ad platform, but it’s only in the test phase.”

So while Seth Goldstein picked up some pub for being the “unofficial” press release of sorts for this next phase of Twitter it is probably too early to speculate on when this will be less talk and more reality. In the meantime let’s see what people are or have been putting out there. The Washington Post reminded us of Robert Scoble’s idea of the SuperTweet he introduced back in November

Robert Scoble, for instance, suggests the idea of a SuperTweet with all sorts of metadata that pops up when part of the message is rolled over with your mouse. This data could include things such as the location of the Tweet and how many times it’s been retweeted, but it could also trigger a contextual ad triggered by certain keywords.

Other questions that need to be considered on how will these ads be paid for. Will there be an AdSense type platform for Twitter users to share in the wealth? Where will the ads appear if they are not in the stream? The list goes on and on.

What are your thoughts on Twitter ads? Are you looking forward to seeing them? Will they impact your Twitter experience? Do you have a particular format that might or might not work for you? Why not join in on the speculation and guessing. Your guess is as valid as the next guy’s right now.
