Currently our lego tag (and related tags) are
a mess something that can probably be fixed fairly easily given that there are around thirty questions overall (this query, courtesy of @SQB, yields 32 results).
Furthermore the tag description for lego is misleading:
Lego is a line of plastic construction toys that are manufactured by The Lego Group. Questions which ask for identification of SF and fantasy toys built with Lego are on-topic, any others are not, and belong on bricks.SE.
... yet only 6 lego questions (out of 16) are ID.
This could be the occasion to assemble a tagging policy for LEGO-related tags.
Hence, what to build with LEGO?
