I decided to do a test run with community wiki on
instead of closing as "Not Constructive" since it's just asking for a list of backup services (to be fair back then even I voted on the question).
So I merged all answers into one. And listed it by type.
The pros so far I see in this is
- having a quick view of what sites are out there without discounting the effort given for finding the apps.
- if a post is made CW from the start, most users may not want to contribute (no rep to be gained)
- it could be an excuse to keeping list questions open
- someone needs to continually maintain it
A suggestion would be to push extended details (what each service does and their limitations) to separate answers. But then as seen with Hidden features of Google Search , one will not be able to control where the Table of Contents are shown (since we cannot force a user to accept a particular answer).
Also if there was a way to control where the contents show up. One could keep the ToC answer CW, leave the rest of the answers non-wiki and ensure users answer with details.
