  • What’s Ahead for chi.mp in 2010

    As we roll into the year 2010 here at chi.mp, we’ve spent some time reflecting on how chi.mp has evolved and what our goals are as a company. To ensure that chi.mp continues to progress we have decided that we need to focus on doing what we do best: give away free .mp domains on which people can build their own personal web sites. To accomplish that goal we’ve begun making changes to chi.mp and will continue to do so throughout the year.

    The first significant change we made was to reduce the amount of aggregated content we store. We found that the vast majority of requests were for the most current aggregated activity items, however we were storing well over 20 million content records, most of which were never being seen. To help stabilize the chi.mp system and improve its performance we reduced the total number of content items that we store in any given service subscription. By making this change we’ve been able to greatly reduce page load times across all chi.mp sites and dramatically reduce outages, which is good for all of us.

    The next major change was the removal of the Ultimate Black Book. Contact management is a business in-and-of itself and to be done right it must be the primary focus of the business. While the Ultimate Black Book is a cool idea we will never be able to give it the attention that it deserves and requires to become an ubiquitous contact manager. To that end we have removed the Ultimate Black Book from the chi.mp interface. If you would like to download a vCard with all of your contacts you can do so by logging into your chi.mp site and going to the View My Site : Following. The full vCard download will be available until the end of March.

    So that covers what has been removed, now here’s what we’re changing and adding:

    First we’ll be completely revamping personas. The current implementation is not being widely used and so we’re going to fix it. We’ll be doing away with OpenID-based log in for your guests and instead let you create custom subdomains that represent your various personas. This means that sharing a persona will be as easy as giving out a URL. It also means that you can have multiple public personas which will open up new possibilities on how personas can be used.

    We’ll also be adding support for subdomains redirecting to other sites. For example, you might want to direct http://photos.yoursite.mp to your Flickr or Picasa profile.

    Both of these features will be available under a new pro package, which will be a paid upgrade for chi.mp site owners. We’re also moving email forwarding to the pro package and will add the ability to forward more than one email address from your chi.mp site to other email addresses.

    You may have noticed that we’ve changed Contacts to Following. We want to make it really easy for you to see what all of your chi.mp friends are up to and thus we’re adding a feature that will aggregate all of your chi.mp friends’ content into a single page so you can see their activity streams in a single location.

    Finally we want to make sharing a more important aspect of your chi.mp site. To do this we’ll be adding a Promote link on your chi.mp site that will provide sharing tools as well as widgets that you can embed on other sites.

    Chi.mp is all about you, and having a personal web site that brings together everything about you on your free domain. We look forward to a year of focus and improvement for chi.mp and hope that you continue to share the journey with us.

    Sincerely,
    The chi.mp Team

  • What’s All The Hubbub About?

    It’s got a funny name, but PubSubHubbub, recently released to Google Code, may prove quite useful. PubSub is short for publish/subscribe, an asynchronous messaging paradigm. A publisher produces messages and subscribes consume those messages. PubSub is often used in distributed software systems as a way for pieces of the application to communicate with each other even though they reside on different computers.

    PubSubHubbub defines a way to publish and receive updates when Atom feeds change. As mentioned in my previous post, Atom feeds syndicate items from places like news sites, blogs and various parts of chi.mp (like the activity stream and blogs). With PubSubHubbub chi.mp could select one or more hubs to publish notifications to each time one of your feeds changes and then subscribers would receive notification and content from the hub directly. The primary benefit of this is that subscribers would no longer need to poll Atom feeds to see if the feed has changed, rather they could simply be notified of the change.

    One interesting aspect of PubSubHubbub is that it does not require a single centralized hub. On the contrary it is designed to allow publishers to select one or more hubs that they publish to, which are defined in the atom feed, and then subscribers that support PubSubHubbub subscriptions can listen for updates on those hubs. The hubs in turn are responsible for checking whether or not the feed has updated and then posting to each subscriber’s HTTP endpoint that they have provided when an update occurs.

    After reading the protocol my conclusion is that this will probably be useful in the future, however right now it’s so early on in the process that the implementation is still a significant challenge, largely due to lack of documentation and test environments. To be fair, there is a test implementation running on Google’s App Engine, however when I tried it out it lacked decent explanation for the various required fields and their expected values.

    The bottom line: PubSubHubbub is interesting but still needs some more time to bake.
