I haven't found much of a change on Facebook.  However, I only use it to keep up with long distance relatives (cousins, aunts, & uncles) and old friends I'd seldom see or hear from otherwise, especially old classmates and coworkers . For that, it's WONDERFUL. 

I look for the humor there and basically ignore the politics and strife.  I shut down drama queens as soon as they are identified.  I simply can't be bothered with energy zappers. 

So, I haven't noticed it there.

Twitter I all but NEVER use.  I only have it for one specific use that is quite infrequent.  But I hear that it's falling apart.

It IS a real shame that Woodbine killed his own board, but it is what it is and that's the end of that.  However, there was a time that I really liked it.  I even liked Woodbine. 

I am VERY sorry that some of the crowd helped destroy it.  If we'd all just left it alone, it might still be there and you'd still be having fun there.  :-(
 

Woodbine's C&E was fine. Especially with the dry, witty British humour. 
The reciprocal ugly American invasion began the wreckage, and Woodbine's delegation of moderation to SUM finished it. I miss the original, but not what it became. 

I tweeted a few times early on. Found it wholly uninteresting and not useful. 
Slowly eased into Facebook. I tend to not jump onto popular trends right away. 
Any hold should be tested before you trust your weight on it.
