Currently, we only have 10 nominees in the Stack Overflow moderator elections.
Granted, it's only been a day, but given the size of Stack Overflow, the moderator election is something that everyone turns out for and we should have a much higher number of nominees for at this point in the nomination phase.
The only difference now is that the notice was put in the community bulletin, which is possibly resulting in a little "blindness".
Given that the moderator election affects everyone who uses a site and that we use a voting system designed to be the most fair as possible (by most accounts), we want to encourage as much participation as possible.
That said, I recommend that for moderator elections on any Stack Exchange site, the link should be put in the community bulletin and the system message should be shown as it was in previous elections, for a period of two days after each phase of the election.
Honestly, I'd do it myself, but given the history of the system message on Stack Overflow (as well as the desire to make this general for all sites), I'm tossing it out for the community and SE to provide feedback/approval/disdain on.
