Along with looking at Google analytics, Google crawl stats, and other server-based statistics we’ve been tracking RSS Mixer’s Alexa Ranking. The figures we see on Alexa are certainly encouraging, even at this early date. (RSS Mixer has been out there for less than a month.)  Yesterday, RSS Mixer was ranked the top 23,527 site in the world on Alexa. With literally hundreds of millions of Websites out there we’re very pleased to see this.

Alexa Rankings are determined by data sent from users who have the Alexa Toolbar and “other diverse traffic data sources.” It is a somewhat imperfect from a statistical point of view–it is not as accurate as server-side statistics.  Still, Alexa does provide the ability to roughly compare the popularity of various sites.  There’s more about Alexa Rankings on their site.

The other statistical information we have indicates the same strong growth for RSS Mixer. Over the next few months, we’ll see if can be sustained.

The public alpha for RSS Mixer has now been up for a week. The site started out with around 18,000 feeds in the directory. These were added over the last year, since the launch of the initial prototype last summer. The count now stands at 24,000–a relatively large increase for our first week. This total number of feeds translates into nearly 3 million posts in the RSS Mixer directory.

A mention in Mashable! (RSS Mixer Makes Mashup Easier), along with a number of mentions in China (most notably Web Share 2.0) and a post in a Spanish language blog (Geeks Room) among others–helped add nearly 3,000 feeds in just 24 hours. Things have slowed down a bit since, but we are still serving up a lot of pages and supporting an ever-increasing number of widgets and feeds.

When the prototype site went live last year, we were swamped and the site was crushed by spikes in traffic. This time around the structure of the application and the database is much improved.  Not only can we handle the load, the time it takes to deliver pages is vastly improved. Take a look at the chart below from Google Crawl stats. This shows how Googlebot (which indexes pages) has spidered the RSS Mixer site over the last 90 days. You’ll notice as the Alpha site replaced the prototype there is a huge spike in activity, as new pages are added to Google. Check out the bottom graph and you’ll see the download time fall off the chart!

This drop-off shows the performance improvement in RSS Mixer. Of course, if we continue to add 6,000 feeds and approximately 750,000 post every week–we’ll have to revisit our site structure in the coming months.

Tomorrow, myself and Chris Gerber, our top Flex developer will be presenting at the New Mexico Internet Professionals Association’s (NMIPA) monthly meeting.  We’re going to discuss Adobe Flex and how we’ve used it in recent projects. For example, the video player on the Open Exhibits Website was created with Flex, as was the Media Player and Web widget for RSS Mixer. We even created a interactive exhibit for NASA using Adobe Flex.  (It will be released in October, and we’ll add it to our portfolio, then.)  If you’re local, join us. There’s more about the event at the NMIPA website.

Mashable! (the #13 ranked blog in the world, according to Technorati) has just written a very positive article about RSS Mixer. Our launch last week competed with Google’s Chrome release, so it has taken a while for the story to get out there. (The lesson here is never release anything when Google has got something new to share.)

In the article, the writer, Doriano “Paisano” Carta, goes through many of RSS Mixer’s features including; widget output, OPML support, and the Firefox Add-on. After all the work, Ideum has put into the site over the last year, it was nice to see positive comments like this one…

“It is extremely easy to mix and mashup many RSS Feeds in no time at all. The interface is well-designed and helps make the process very simple.”

If you have a Twitter account, you probably already have blog, a Facebook page, a Flickr account, a YouTube account along with other points of presence on the Web. For many of our museum clients, managing this extended presence with limited resources is a constant challenge. So anything that comes along that makes this process easier is of great interest.

This week we created a Twitter site for RSS Mixer. I wanted to find a way to help keep this Twitter site up-to-date without having to manually enter every update. I came across TwitterFeed which takes your RSS Feed and automatically posts updates to Twitter. It is simple to use and while it isn’t a replacement for manually adding updates, it certainly helps and saves you having to manually update every blog post to Twitter.
