This website is overflowing with information from how to chose a baby name to calendars to predict ovulation and pregnancy due dates. It has all the basics like articles, and a forum, but what I enjoy most about this website is the blog. The Mominformation blog over at Baby Center has a wide variety of candid articles from real Mom's. I enjoy the opinion based articles, and pop over to the site from time to time to see what is new. They do also have giveaways which I rarely find time to enter, but if you are seeking out some to enter this is a great website to add to your list.
The forum on Baby Center is very active, and a great way to connect with other Mom's and Mom's to be. They have specific groups you can join such as Birth Clubs, Stay at Home Mom, First Time Mom, etc to customize your experience. When you visit each club you will automatically see all of the latest chatter. I find this forum really useful if you want a quick answer to something that is on your mind. The constant activity allows for a variety of people to answer your post. The only downfall to constant activity is that it is hard to keep up with.
This website is a great resource for pregnant women, women trying to conceive and is even still useful into childhood.
