Same question as cjohnson318's. What are some low hanging fruits in mathematics? I have been looking for them for a few years now and have found none.

  See my reply to cjohnson318 for an example.

  Very recently the superpermutation problem [a.k.a "haruhi" problem]. Obscure enough that a anime-loving anon gave a proof for improved bound that went unnoticed for some time.
