Don't you guys think that it would have been great had we had a chance even to text the friends we meet here?

Question

Why not text?

Answer 1

Well, you can do it here on Q&A, or comment on their codes. Else, you could chat on another third party service.

...I'm sure Sololearn are working on it though

Answer 2

As Ahri Fox correctly pointed out, there are enough resources for interaction between users. Some of these need some refinement, that has to be applied, keeping in mind that too much social components, end up with entertainment prevailing over education.
Since Social Entertainment is already widely available outside of SL, lets keep SL on the educational side.

Answer 3

okay, got your point :)
