I have gone through the nomination page and questions asked to the candidates. My choice would be Nataliia Tymkiv and Kunal Mehta.
Both these candidates are well aware of the declining relationship among community, staff and WMF and want to solve them in a transparent wiki way. Both their answers seemed practical to me and I think, if they are selected, they would make a difference.
Kunal Mehta is a WMF staff as well as an active Wikimedia volunteer, a
combination we obviously need in a BoT member. He has closely observed
the crises built in foundation and in my opinion, has more insights in
this matter than other candidates.
Other candidates, except few, are also active Wikipedians in their way and if I had another option, I would preferred Osmar Valdebenito.
Satdeep and Sudhanwa preferred Siska Doviana. With all due respect, personally I am not fond of
those Wikimedians who are not/less active on-wiki and still
are/were EC members of different Wikimedia chapters. I know, that global
edit-count is not the best indicator for Wikimedia involvement, but
on-wiki involvement helps Wikimedians know the dynamics of the
community, realize common community problems by heart and look for
solution collaboratively. To me, if you are an EC member, then you have
more reason to edit on-wiki (not only meta), because that only makes you
build the bond with community members.
