I have recieved a few questions about the current state of FavoriteSync:
FavoriteSync is not in active development anymore and has not been so for the past half year or so. This is partly due to the limited time the developers have and partly due to the fact that it is a "semi - nonprofit" (barely surviving to pay for the server from subscriptions) effort. It might have been possible to steeply increase the fee and provide more support but the current thinking is to keep it as cheep as possible and live with the current set of issues.
Having said that, there is no plan to shut down the current service which has (with the exception of the 06-07 new years weekend) been highly available throughout its operation.
There might still be future extensions, modifications to the software but there is nothing currently planned.
