Here's how you use Google Weddings to help plan your big day:
Create a free website with Google sites: You can create a free website using Google sites and it's actually pretty easy. Of course it won't look nearly as good as a web designer could do — but like I said, this seems to be good for those who don't have people in the industry to help them. There are detailed, step by step instructions how to edit the website and customize it to your liking.
Make announcements using Picnik: Create free announcements of any kind and save them as images on your desktop. Easily upload pictures, text and backgrounds. You can upgrade your membership to Picnik for more options.
Organize the to-do's before the I-do's: Using Google Docs you can organized any aspect of the wedding planning. Things like budget and seating chart are great for Google Docs!
Save and share memories using Picasa: Upload and create albums easily in Picasa. We all heard about Picasa back in the day and it's actually still around. It's a great resource for people who want to upload and edit photos without having the skill set or time to use Photoshop.
All in all, I don't think I would personally use Google Weddings but I would certainly recommend it to friends who aren't in the tech, web or design industries.
