I like the concept of the overarching net and the wave shape in #1, but at the moment it looks a bit mechanical/technical-drawing, non-living. Someone here also mentioned it could be taken as a fishing company logo- we don't want the idea of catching stuff, but rather of connecting knowledge etc. Difficult, but if you could come up with something softer and more natural looking without it looking like a resort, I'd be interested to see it (you may have figured out there are 2 of us providing comments on this logo from the same office!).
Also, light blue might look softer, and/or use of a less rigid font and lower case?
