I always love going to the source. Let's encourage one another to read the Bible.
"Encourage one another and build each other up."

I would be fine with reading about 3 chapters a week.

Along the same lines, an idea came to me that we could do Bible Reading Plans.
Zondervan has several Bible Reading Plans. I was particularly thinking about their 2-week reading plans.

Here's an example of a 2 week Reading Plan:
Two Weeks on Prayers of the Bible
Day 1, Genesis 18: Abraham's plea for Sodom
Day 2, Exodus 15: Moses' song to the Lord
Day 3, Exodus 33: Moses meets with God
Day 4, 2 Samuel 7: David's response to God's promises
Day 5, 1 Kings 8: Solomon's dedication of the temple
Day 6, 2 Chronicles 20: Jehoshaphat prays for victory
Day 7, Ezra 9: Ezra's prayer for the people's sins
Day 8, Psalm 22: A cry to God for help
Day 9, Psalm 104: A prayer of praise
Day 10, Daniel 9: Daniel's prayer for the salvation of Jerusalem
Day 11, Habakkuk 3: A prophet's prayer of acceptance
Day 12, Matthew 6: The Lord's prayer
Day 13, John 17: Jesus' prayer for his disciples
Day 14, Colossians 1: Paul's prayer of thanksgiving

We wouldn't have to do the reading in exactly 2 weeks; we could spread it out over a longer period of time. I thought I would mention this, because it's sometimes nice to read more areas of the Bible. I'd also be good with just picking a book in the Bible and reading it. The 1, 2, 3 books of John are a great place to start.
