Personally I have been a SAP BASIS guy 15 years. As you might imagine that means lots of time troubleshooting notes, sdn, scn etc
I was not a great fan of SDN in the end but I could find stuff eventually. SCN is an utter disaster.
1/ It takes too long to find anything. At least we could search by forums. But now its "spaces". Searching for the right "spaces" takes too long as we have to load a small number of "spaces" per page along with the last post. The search function is useless as who knows the exact keywords in the "space" name.
2/ Moderation - drop the long wait for moderation and drop the 30 requirement to avoid moderation. Other sites deal with spam etc OK and do not force us to perform juvenile tasks to get badges. I work for several clients a year and having to go thru these childish games is pointless.
3/ I have seen a marked drop in technical posts as people turn to the many other sites that support SAP.
All in all these changes are killing what was once a mildly useful resource.
Who agrees with me.....
