Delphine:
I find it indeed important that in the case of paid developpers (which, imho there should be more of) the development needs addressed be that of as many "communities" as possible, so that no project feels left out in the end.
That's why I want to organize community meetings as soon as possible, where we will discuss with members of each community the needs of their project.
However, in the light of what has been said on the other threads about official positions, I find the use of a logo quite strange.
The logo says "Research", it can be used by anyone in the Wikimedia context for research-related activities. Note that Jakob placed it on the general [[m:Research]] page as well without being a member of the team.
