I am aware that Wikipedia contains pages that have very little content. If you are a part of the Wikipedia team, you would also be aware that these pages are regularly reviewed, critiqued, and occasionally removed due to the lack of content. We attempt to monitor such changes, but since we are not directly partnered with them, it is difficult to note when pages are removed until typically long after the fact.
However, from those you cite, you imply that we should aspire to the lowest common denominator as it relates to holding to a Wikipedia page that may end up on the chopping block. What we do here is what WikiTree has always done - attempt to properly document a profile so that all who view the profile can agree that it meets or exceeds the standards. Wikipedia and WikiTree both agree on basic principles. Sources. Content. Standards. There has to be documented evidence of notability. The biography must cite the items of notability. And it must meet the standards of notability. If, as with Wikipedia, a few years later neither you nor I are here to defend such a profile, and a new team comes in and asks "why was this Notable?", then I would hope that our goal would be that it would have at least a reasonable defense to present and would not be swept away.
I would also argue that unfortunately, election to a legislative body at the state level in the United States is not a high bar, as there are at least tens of thousands who meet that criteria, although if Wikipedia acknowledges it, I will not argue in that respect. My feeling is we should operate within the standards we've agreed to, and if we disagree with those, then operate to change them. However, their standards also acknowledge the items mentioned above. Sources. Content. Standards. And those are absolutely needed. While it is tempting to claim that the little old lady down the street who always opened the library on time and was friendly to everyone who she met was notable in their eyes, we do have to draw the line somewhere, or else everyone is notable, and by that principle, no one is Notable. But I believe we should aspire to higher standards where we can, prove as much as we can, and when others attempt to understand why we made our decisions, then they will stand on their own merit.
