At the end of Round Eight there were a lot of books owing to or from most VBB participants. After a protracted break the owed books list is a lot shorter.
Personally, I hate having a huge stack of MUST-be-read books so I try to minimize the TBRs I offer here.
This isn't a hard-and-fast rule but I'd like all users to consider restricting their VBB offers to books they have already read, or books which can be read within a couple of weeks of being offered. If we all do this then everyone should receive their selections sooner.
