Possible Mapping of Questions to Grouping:

T1 Ease of posting / Technical expertise / Familiarity with the technology / Speed of accessibility

2, 19, 20. 42, 69, 70, 71, 109, 124

T2 Number of possible connections (also the common demoninator aspect)

75, 77, 81, 121, 123

P1 Sense of community /  Inclusive/exclusive relationships

6, 13, 49, 76, 111

P2 Strength of relationships / Proximity/closeness

8, 14, 15, 48, 103, 141, 142

P3 Tone of communication / Establishing presence/voice

43, 44, 7, 11, 45, 47, 57, 66, 88, 89, 97, 105, 106

P4 Sparring / Challenge

73, 74, 10, 83, 116

C1 Location of ideas

17, 18, 78, 85,

plus something from the discussion Part 4 Draft 4 like "love to bring numerous topics to the table that are strongly tied and obviously related, and love to have all the aspects in on spatio-temporal place"

C2 Diversity of discussion/ideas / Convergence/divergence  

21 - 25, (31), (40), 131 - 134,  

plus something from the discussion Part 4 Draft 4 like "love to relate to more distantly related, distributed ideas, and the conceptual connections are initially weak getting stronger by reflection", plus something from Thought about Part 4, Draft 4, Point 4 like "what type of diversity (multi-facet or initially distant), and what type of depth/ strength of the conceptual ties, (implicitly preset closeness and synchronicity, vs. initially weak and strengthening).

C3 Speed of conversation / Pace

3, 52, 54, 72, 110

L1 Autonomy/control / Self-expression / Freedom of choice / Ownership

33, 34, 46, 50, 51, 55, 56, 59, 60, 61, 62, 107

L2 Reflection

27, 28, 29, 53

As for the remaining questions, I think they address more than one of the above topics, or none of them, and would probably need to be rephrased to be better iterpretable afterwards. (However, considering all those numbers, I have certainly made some mistakes, so please do doubt my suggestions.)
