It still falls short. For instance, looking at the Lord's Prayer (Matthew 6:9-13), there are 19 links in the ESV, which point to a handful of Factbook articles.
Our Father in heaven, hallowed be your name. Your kingdom come, your will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from evil.
The links add up thusly:
Disciples: 7
God: 8
Earth: 1
Food: 1
Sinner: 1
Satan: 1
What's missing? Links to the Kingdom of God, the will of God, heaven, debts, and temptation, all of which have Factbook entries, and which would have been far more beneficial than 8 links to God and 7 links to the disciples. I hope that this is still an early stage of the Factbook link, but right now it's of very, very limited value.
