Ashley The current system is inherently unfair to users who submit their ideas later in the year. These suggestions often don’t get enough exposure before the annual reset, meaning excellent ideas risk disappearing unnoticed. Meanwhile, mediocre suggestions are repeatedly reposted at the start of every year, cluttering the list.
A 12-month expiry period for all suggestions would ensure equal treatment, as every idea gets the same amount of time to gather votes and attention. At the end of the 12 months, the number of votes would accurately reflect the suggestion's usefulness and popularity. You could then decide the next steps for most popular suggestions — whether approve them for development or decline and archive.
This approach could also help reduce the number of reposted suggestions, which aligns with your goal of keeping the list short and relevant. If users see that their idea hasn’t gained many votes in 12 months, they’ll be less likely to repost it, as it no longer provides the advantage of being at the top of a freshly reset list.
