There's been quite a bit of controversy over the past several hours over words and images related to Twitter being used by third-party developers. Yesterday, Twitter seemed to threaten one party over the use of the word "tweet" and some UI elements that were similar to Twitter's own. This morning, Twitter co-founder Biz Stone clarified Twitter's position on this a bit for us, stating that, "As part of this support, we encourage developers of new applications and services built using Twitter APIs to invent original branding for their projects rather than use our marks, logos, or look and feel." But there was still some confusion about what Twitter was actually saying, and more importantly, what it was planning to do with violators of this.
