SparkleShare is Mono (and proud of it), Ubuntu still under threat of having Banshee spread throughout the project, putting in it code which Microsoft explicitly stated is a patent problem

Canonical's Gerry Carr said that Ubuntu was not deliberately looking for Mono-based applications nor is it excluding them. The Canonical Board has yet to make a policy decision on Mono. He said that there will be one more piece of Mono based software called Banshee in 9.10. Banshee is an audio player and might replace Rhythmbox.

Just have a look at what will be gnome 3.0...here is it.. And along with the controversy found with Mono. Richard Stallman, a member of the GNOME Foundation, has said that GNOME 3.0 will include more applications made with Mono: "The only application that Mono is now part of the whole launch is Tomboy

Refutation of Mono disinformation about Banshee being a GNOME project without associated issues

Banshee is going to be the default music player for Ubuntu which makes me worry. Banshee is based on the controversial Mono technologies developed by Novell employees. Richard M Stallman has warned against Mono and C# which applies to Banshee as well.

Banshee is a music management and playback application for GNOME. Over the course of the year a variety of high quality, highly polished, and all around “swell” Mono GNOME Desktop applications have been popping up. As with many of these apps, Banshee has a beautiful user interface and is well architected. This article describes installing the latest version on Arch Linux and OpenSUSE 10.3

When you think mono, you think tired. You think sleepy. You think shut-yourself-up-in-your-bedroom-for-two-weeks-and-snooze-like-Rip-Van-Winkle. You get the idea. But that is not how it should be. Mono isn’t boring. Mono should excite people!

A bizarre decision is made just weeks before the final release of Ubuntu 10.04 because an F-Spot (Mono) competitor is removed and Banshee (Mono) gains integration with Ubuntu One
Steven Rosenberg has just published a rave (finally!) about Ubuntu 10.04. He particularly likes gThumb, which can help remove Mono from Ubuntu.

Before I begin this essay, I would like to go ahead and pre-empt any attempts to make me out like I’m a Mono shill. I’m far from it. The only application that uses Mono that I found remotely useful was F-Spot. I see no point in running Tomboy when I can just use Gedit (since files are opened in multiple tabs, just like EditPad).
