There is hardly any forum which can beat the bitcointalk in all aspects. We should always keep in mind that this forum was started by the Satoshi and hence there could not be any alternative.
Sorry I do not agree with this point given you. I appreciate the work being done by staff on this forum. But if you think that this forum will remain number one just because it was started by Satoshi, it is not practical. One has to keep up with the changing trends. For instance, at the time of starting the forum, he might not be expecting sections like alt coins here.
