Over on his blog, Bruce Elgort asserts that voting on idea jam has come to a halt.
And he asks why. The common consensus appears to be that it's because nobody saw that it made any difference with the product.
That might be a completely valid assertion. I cannot remember when Idea Jam went live. I think it was right around the time that Notes 8.0 shipped, or shortly thereafter.
Let's say it was about a year ago. In that case, it was too late to influence anything in Notes 8.0, and we've shipped only a point release, Notes 8.0.1 in the meantime.
We have been trying to get a few things (most notably the number-one voted client thing, the roaming html signature-- or something like it) into Notes 8.5.
It still takes a while to get something into a release cycle (We are also working on making them shorter/doing other inventive things).
So please do not abandon voting on Idea Jam just yet, and don't stop responding to this blog, because your feedback can still honestly make a difference.
