Many other people are holier, funnier, smarter, and better writers than I; here are some sites that you should probably check out:
The Happy Catholics - a group of Catholics in CA who work tirelessly for the rights of the Unborn.
Conversion Diary - A cool, new take on living as a Catholic wife and mother.
Happy Catholic Blog - not to be confused with above, interesting, well-written ideas about living as a Catholic.
The David and Craig Show - Family-friendly, funny, Christ-centered podcast.
For Your Marriage - Awesome Catholic-run website on the Sacrament of Marriage, starting it right, keeping it Christ-centered, and keeping it going through years, children, and whatever comes.
St. Blog's Parish - A list of many Catholic blogs, maintained by everyone from clergy to laypeople (what what!).
Daily Readings - Official USCCB site with daily readings and psalms
Liturgy of the Hours - A site with all the prayers of the Divine Office
The Catechism - Again, official USCCB site, full text (just in case).
Anything else I ought to be reading? Let me know, I'll check it out!
