ReadWriteWeb has an interesting entry that says that photo sharing site Slide.com has moved into second place behind only Flickr — in New Zealand, anyway. 

One interesting nuggest is that Slide.com gets 59% of its traffic from a collection of small Facebook applications they’ve created.  These applications are being widely adopted on Facebook as a great way to share pictures.  Clearly Facebook’s application strategy is paying dividends.  Less clear is how this strategy is going to play out for Slide.com, which reports that their average time per visit on the site is much lower than other photo sharing sites.  On the one hand, this may be a great thing for the visitors: they are getting more value for less of their precious attention.  On the other hand, is Slide.com going to get the benefits of all those users, or is Facebook?

Another interesting nugget is that Slide.com is making so much progress in New Zealand — but apparently not everywhere.  Will photo sharing be another domain, like social networking, in which geography determines use?  There are network effects in photo sharing, since it’s more convenient to be in the same network as the people I like to share photos with, though the network effects should be less powerful than in social networking, since I can still share photos with you even if you’re in a different network.

An interesting research project would be to track the evolution of these geography effects across time.  One hypothesis is that people are always going to have strong ties to people they’re physically adjacent to, in which case these geography effects will be enduring.  Another hypothesis is that heavy net users will tend to have relationships that are more independent of geography, in which case these geography effects will decay in importance with time. 

Any predictions?

Another interesting ReadWriteWeb article, this time on how life is shaking out in the social bookmarking world.  The article has a number of interesting types of analysis, but the main focus is on user-ship.  On this dimensions, del.icio.us dominate, with more than 10x more users than the next best (Magnolia). 

My predictions is that there should be a moderate vortex effect in social bookmarking, with benefits to the category leader because of the greater volume of other users creating value by adding their bookmarks.  On the other hand, in the absence of true personalization in this category, the vortex should be limited, since above a critical mass the additional users add more noise than additional value.  In fact, we should expect to see a number of secondary social bookmarking sites spring up with the goal of attracting a clientele that shares similar tastes.  In a sense, this will let people find their own "neighborhoods" of others with whom to share bookmarks, rather than sharing with the unwashed masses.  Unlike with automated personalization, these neighborhoods will most easily form when they are structured around easy-to-understand syntactic categories, so the usual suspects — religion, politics, and sex — seem most likely as the fracture points.  

No, it probably is not coincidence that these are the traditional "off-limits" topics for casual conversation.  These are topics about which people prefer to talk to people with whom they agree.

I’d personally rather see a more personalized approach from one of the top social bookmarking sites.  Such an approach might lead to a much stronger vortex effect, and the opportunity to dominate the category.

ReadWriteWeb talks about a new feed reader that has strong social features, making it easy to share items with other users in rich ways.  They say that FeedEachOther also has interesting recommender algorithms to help people find other feeds to read that are similar to feeds they have read in the past.  Sounds very interesting!
