NO: we should stick to the current threshold of 5.
I have noticed wayy too many circumstances in which a question was being voted to be closed by 2-3 users inappropriately (i.e., the close votes were unfounded/not supported or the wrong close reason was chosen). Reasons for these inappropriate VTCs range from novice voters, rushed voting, malicious voting, and difference of opinion. By reducing the close-vote requirement, we will undoubtedly close more questions that do not fit the description for being closed.
We have two current problems on this SE site: (1) lack of review tasks being performed by current community members, and (2) decline in engaged users (+ an overall drop in visits overall!). I think this current VTC proposal is indirectly trying to account for these issues.
- A 3rd issue is that the overall quality of posts has declined sharply in the last 2-3 years. I (among others) still hold posts to a higher standard based on older expectations of this community (i.e., one for scientists). Truthfully, the community has shifted much more toward consisting of novices and students here asking simple questions. At some point, our expectations just can't outweigh the masses asking the questions... [I digress...]
However, I don't think the close-vote proposal will have the intended effect. The root of our problem is community engagement. By changing the VCT threshold we would not be changing that engagement level. Instead, we would be allowing decisions for the whole community to be made by an [even fewer] select active individuals.
We have a community engagement problem on Bio.SE (perhaps an irreversible one), but I don't think the current proposal will fix that root issue. Instead, such a proposal will just give more closing power to the select individuals (<1% I'm sure of all users) who do vote. I'm afraid that such "power" would come off as a form of elitism as it does on some other SE sites, and may even result in a further decline in community engagement.
