Our "All Review Requests" page in https://git.reviewboard.kde.org has 13 pages of reviews, when sorting by "Last Updated" you'll see that from page 1-6 are reviews that have been updated in the last month, 7-8 in the last two months, 9-12 in the last year and 13 in more than one year.
That's a *lot* of reviews that either where not reviewed at all or where not followed up.
Please, people, pay attention to reviews, if stuff needs to be improved (either if you are the submitter or the reviewer) do speak in a timely manner so we can get stuff commited as nicely as possible.
Let's make the world nicer and review other people's code when they ask for it :-)
Otherwise i'll start closing review requests as discarded because what's the point of having stuff there rot that probably doesn't even apply anymore? ;-)
