SL residents have been understandably frustrated by bugs in SL. The friends listings are flaky, people report losing things from inventory, teleporting is an iffy thing.
One result has been the notorious "Open Letter" that requests that certain of these problems be fixed in preference to the addition of new features. Unfortunately, despite LL's having devoted over two thirds of its development staff to bug fixes, there appear to be vocal people who object to any development of new features.
News flash: no large program is bug-free. If you insist that all SL bugs be fixed before any new development occurs, then no new development will ever occur. Such a demand is short-sighted. Those interested, and those complaining that 69% isn't enough people to dedicate to bug fixing, might also wish to learn about Brooks' law.
P.S. There's a certain irony in the fact that the majority of SL users, and hence probably the majority of the complainers, are running Microsoft Windows.
