Right now, the only way to share a link directly to a suggestion is to copy the URL from the address bar and paste it elsewhere. It would be easier for users to do this automatically if there were a "share" button that automatically copied the page URL to your clipboard.
(This would be even better if there were a shortened version of the URL people could use, e.g. in chat/social media applications with character limits. But that might be better as its own idea so I'll suggest it separately.)
