In the last week, an average of only 2.2% of visits were on IE8, and this is continuing to drop. We don't take the decision to stop supporting a browser lightly, and even though we're dropping active support for it, that does not mean we will ignore critical issues if they occur (similar to how we currently treat Opera).

Essentially, there will be no sudden change tomorrow - Wikia will continue to work as it does today on IE8. However, problems specific to IE8 will be lower priority.
