goodreads vs. shelfari

I love online communities. Most people find them stale and uninteresting, but I think they're awfully fun. You can join groups, take quizzes, fill out profiles, and add 'friends'. You're probably thinking of Facebook and Twitter, right? Certainly those are the major ones on the internet right now, but what about a networking site that's all about books? Whaaaat?
It's actually quite interesting. I'm going to focus on two particular sites: Goodreads and Shelfari. Here are some photos to demonstrate:

Here's the goal of these websites in a nutshell: to help you organize the books you've read, write short reviews and rate them between 1-5 stars, compile a list of books that you want to read, and connect with friends over reading. I've got an account on both sites, so I can go at this fairly.

Goodreads:

Here are the good things about it:

-It has more of a community feel, with tons of groups to join, book polls to vote on and quizzes to take.

-You can browse through pages and pages of quotes, and add them to your personal collection. 

-It encourages members to add their own writing, and to critique others on their writing.

-There's more emphasis on 'friendship'.

-There's something called a 'book swap', in which a person puts some of their books up for 'swapping'. You request it, they ship it to you, you pay for the shipping, and viola! You have the book.

Some bad things:

-It's kind of hard to navigate around in... 

-It's tough to find and add books to your library.

-Once you get them, it's difficult to view them.

Shelfari:

Good things:

-This site is generally much easier to move around in. Plus it looks much cleaner and simpler.

-It has a virtual shelf on your profile, on which the books you added rest (something that Goodreads lacks).

-The books are divided into three sections: I've read, I'm reading now, and I plan to read.

-It's very easy to add, rate, and review books.

-You can 'favorite' books, which automatically puts them on a specific list.

Bad things:

-There's nothing for writing... :(

-The profile options are somewhat limited.

If you've read thus far without falling asleep, let me summarize what I think of the sites:

Goodreads is a community-centered site with great ideas, but a lot of the time it's poorly executed.

Shelfari is a more book-centered site that looks much better and is easier to navigate around.

If you're a book lover, I urge you to check these out! Like I said, I am a member on both, so do add me if you make an account on either :)
