On why social networks interoperate… and why not
I came across an interesting analysis about why a social network would open itself to interoperate with other networks… and why not.

As Buth Bebo mentions,
The economic logic behind these positions is a straightforward application of Metcalf’s law, which states that the value of a network is the square of the number of nodes in the network*. A corollary to Metcalf’s law is that when two networks connect or interoperate the smaller network benefits more than the larger network does. If network A has 10 users then according to Metcalf’s law its “value” is 100 (10*10). If network B has 20 users than it’s value is 400 (20*20). If they interoperate, network A gains 400 in value but network B only gains 100 in value. Interoperating is generally good for end users, but assuming the two networks are directly competitive – one’s gain is the other’s loss – the larger network loses.
I liked this analysis as for what would happen if Google Me becomes a success…
When Are Facebook Users Most Active?
An interesting study by Vitrue suggests that users engage the most while at working hours.

Comes at no surprise to me, as while trying to optimize a site targeted at women, we found that the most traffic happens at 10am, 2pm and 5pm, the typical hours for a break in the site’s geography.
The study goes beyond that and finds that Wednesdays at 3pm is when the traffic peak happens, for the whole week.
A few interesting conclusions:
- As social media becomes part of our lively interactions, it is to expect that, as email, we interact with it while we are doing our daily tasks.
- Interesting findings for brands on how.. or better said when, to engage with potential consumers…
