Just thought about this.
I could be useful to also scrape the number of relation a profile has.
Simple observation: sometimes we don't want to add up profiles with only 10 relations but instead the people who has a few hundred people or more in their networks.
Why? Because if this profile adds me, I can access more people.
So we can concentrate only on the people with the larger networks to unlock more 2nd relations.
I know it's not how Linkedin was design in the first place but it's a strategy that works on all other social networks and could do wonders here (where linkedin sucks big time for B2B lead gen, you get contacts but so many limitations).
What to you think of it?
