I’ve done an initial brain-dump into the wiki. Please expand on it and make it prettier as you see fit!
Touch Events Community Group
The Touch Events community group was formed by members of the Web Events Working Group (responsible for the Touch Events specification) and the Pointer Events Working Group (responsible for the Pointer Events specification). The group's focus is to determine differences in touch event behavior between browsers. The group seeks to form consensus on the best approaches for interoperability outside of what's already standardized.
As developer focus has now shifted towards taking forward the Pointer Events specification, this community group is primarily acting as caretakers to maintain and, where necessary, update the Touch Events Level 2 group report, to reflect browser implementation reality. There are currently no plans for any new feature development as part of this group report.
Note: Community Groups are proposed and run by the community. Although W3C hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.
