I prefer having both. Perhaps there's some opt-in/opt-out flag that allows you to not make clickable links. But having a database with most common errors sorted

I prefer having both. Perhaps there's some opt-in/opt-out flag that allows you to not make clickable links. But having a database with most common errors sorted by programming experience in that particular language might be quite useful. I wouldn't be surprised if it would allow a programmer -- being a beginner in a new language -- quickly find his/her mistake most of the time.
