I’m starting a new post series called “Things Twitter helped me discover” to highlight all of the great sites and other things that I find out about on twitter.

The first is Smarty Pig. Smarty Pig is a savings account with social aspects. This all started when I asked twitter if there was a way for me to save for specific goals and let other people also donate money towards those goals. Sure there were things like ChipIn, but that was only to show progress in collecting money, I wanted to also show my own savings progress. So someone suggested I check out Smarty Pig.

When you create a Smarty Pig account, you are actually opening a real FDIC insured savings account that has a 2.01% APY. Then within that account, you set up specific savings goals. That can be a family vacation, college savings for your children, or maybe just something you want to splurge on.

You set up these savings goals and choose how often you want to contribute to that goal, and how much. This was perfect for me because it allowed me to take out an amount from my check each week to save for rent, and then at the end of the month, I had my rent money without even thinking about it.

Next you can choose if you want to make the goal public or private. Certain goals like my rent, I kept private. But for other things, like my trip to SXSW, I can keep it public so that my friends and family can help me save too.

Once you reach your savings goal you have a few options. You can have the money deposited back into your checking account, Smarty Pig can send you a debt card with your savings, or you can choose to receive up to a 12% cash boost on your savings by placing it on a retail card like Amazon.com, Best Buy, Travelocity or Macy’s. You can even spilt your savings among the three, to find the best option for you.

You can add widgets for your facebook or blog so that all of your friends can help you save. I put one in my blog footer.

Many people have been talking about twitter’s new RT beta feature and it may seem like most people don’t like it. But I thought I would throw my 2 cents in the ring about what I think of the feature.

In case you are unaware, Twitter is rolling out an official retweet feature that is in beta right now. It allows users to RT with just one click (no more copying and pasting tweets), and it provides a way for people to easily see how much their tweets are being retweeted.

Now there are some obvious drawbacks to this. The new feature only lets you RT the tweet as it was originally written, you can’t modify it or add your comments. For some people this is a drawback, but for others it’s a plus.

It’s a drawback if you frequently like adding comments to the things you RT, and it could be positive because tweets no longer need to be short enough to add your username to be “re-tweet-able”. A tweet that is exactly 140 characters can easily be retweeted now, where in the past it would have needed to be shortened to allow space for RT @that persons username.

One reason that I like the new RT feature is that it helps to regulate fake RT’s and is a great way to discover new people to follow.

A few things I would change:

1. Avatar correction. I would want the avatar to be the person that I am following who is choosing to share this information with me. After all, the people I follow are people that I trust. So seeing what they retweeted to their followers should be reflected by showing their avatar in my timeline.

2. RT alerts. Similar to the way that Tumblr shows users alerts when someone else has liked or reblogged your post. If a simple one line alert showed up in my timeline letting me know that my tweet had been retweeted it would make the whole process easier and more encouraging for users.

3. 3rd party support! Currently desktop and iphone apps are not taking advantage of the RT feature because it is so new. There is no place in tweetdeck or tweetie for me to see my retweets the same way I would see @replies. In fact, if someone retweets a tweet that has my username in it using the official RT function, that tweet won’t show up in my @replies of a 3rd party client at all.

The fact is that it will be very hard for twitter to rope in a feature that was created by the users and standerdize it. That can’t force you to stop retweeting the old way, so they new way will be hard for people to adopt.

What are your thoughts on the new feature?

Let me know in the comments.

Twitter lists opened up to a somewhat wider release yesterday. I’m still not sure if everyone has it. But once twitter lists launched I couldn’t help but notice one thing.

There are all the times people have put me on their list, right next to my followers. I couldn’t help but think, will being “listed” become the new benchmark people measure twitter success/popularity against?

Suddenly I wanted to see how many times other people had been “listed” and what lists they were on. It wasn’t about what lists they made anymore.

Then I saw this tweet from Alex Hillman,

Twitter lists illustrate the most important shift in the internet: your bio is now written by others, and what they say about you.

Take a look at some of the lists I’m on:

It’s true, I’m a blogger, I live in Philly, I’m noisy, I’m in “techmedia”

When you look at it that way, lists say a lot about you!

How do you think lists will change twitter?

What has it changed for you already?
