Let's get back to learning!
I'm just a newbie on SD and I have the utmost respect for the fluent speakers like Heidi, Lazarus, cogumela and others who have contributed so much for so long. But now I want keep learning, so let's move on.
I've noticed that those who are leaving the site continue to post answers and questions, but usually to disparage the site. But, SD is still very useful to some of us--this morning I used it to help complete my homework assignment.
So let's move forward in a positive way and let's use "feedback" when we see problems or want to suggest improvements.
That's two-cents worth from this unworthy beginner. 
Note: In deference to, and with respect for the many differing comments and notes I had on "eso sí que es" I have removed that expression from my post. Now, let's get back to learning.

Frank, I believe Cogumela is right: I do not think that you can use "pero" + "eso sí que es". I think "eso sí que es" is used by itself; it appears to be an interjection, which is why DJ_Huero's joke the man exclaims, "íEso sí que es!". With "pero" have to use "lo". But again, I am just a beginner, and, of course, there were no frequent moderators to correct me.
But, as has been said ad nauseum, that highlights precisely what has been happening with this site. With most of the experienced native and advanced Spanish speakers gone, there are few left to correct those of us who are hanging on a bit longer.
I think the reason there are so many "new users" is that those who left were frequent posters, whose love of learning and educating, made them proffer their knowledge throughout this site. Sadly, that does not happen anymore. There are many more unanswered threads, and threads with questions that have gone uncorrected. Unfortunately, I believe among the reasons for so many closed threads is that the new moderators/management cannot handle the round-the-clock monitoring of this site. In my opinion, one beauty of the site under the former moderators was they were an international team; by being scattered around the world, there was always somebody awake posting. Not so any more.
As with you Frank101, I am still new here and I want to learn. But with the loss of great threads and an international moderation team, it has become a less enjoyable experience.
Pero eso sí que es ??
Well, I think you mean:
Pero es lo que es.
Don't you?
Here is another proverb for Mariana:
"Why can't we all just get along?"..........Rodney King
i agree. i knew them from years ago and then i fell off for a minute and now i'm back. well i didn't stop speaking spanish because Heidi and her gang wasn't in my life.
besides...Heidi and her gang said they was going to Skype or whatever to start they own show so everybody who want to be with Heidi and Marianne and Lazarus and the rest the gang, go to Skype.
the rest of us who are interested in learning spanish are gonna stay right here. this is as good a site as any and there are many good instructors yet around here.
so let's just get back to work.
