[Features] Reader 'crossposted to' section

I assume that this has been suggested before, but...

With the 3/5 limit to how many tribes a 'snap' can be posted to, and the rising number of tribes due to influx of new users, I think it would be valuable if 'readers' of a snap could 'crosspost' it to other tribes.

This 'crossposted to' section could be separate from the main 'published to' section, which would be chosen by the submitter themselves, and could still have the 3-5 limit.

I've seen numerous comments mentioning that they hit their limit, so couldn't publish to a particular tribe.

This not only would alleviate that annoyance, but it would also encourage growth of smaller/newer tribes. Currently, if I'm posting a snap, I would tend to choose the larger and more active relevant tribes, rather than smaller tribes, so there is a 'false inertia' for small, new tribes in that regard.

Just a thought, and I assume it's been mentioned a thousand times before and there's a reason behind not wanting to do it.
