I read forums.oracle.com frequently. I have read and answered thousands of questions there.
Those days, they launched a new release, I do not know what the improvements are, but it is fairly unstable. Well, it has been worst in the past, but I keep getting We’re sorry, the server encountered an unexpected condition and timetouts occasionaly.
Another nightmare for users was the blank-trimming effect, it was hardly possible to format the post, all multiple spaces were trimmed to one space, even by using [code] or [pre]. It is now fixed!
There has been also two new icons, Usefull answer and Correct answer, but it has been removed already. It makes me remembers the smilies they introduced in a previous release, where :p bind variable was translated to a smile...
Problem with the downtime is that the experts go away. I post and read hundreds of messages on metalink, especially in sqlplus and plsql forums. The problem on metalink, lot's of users expect to have an immediate and advanced answer from Oracle, because they pay for support, and they do not invest time to write the question properly nor to say please or thank you.
I recently start writing on the linux and oracle forums of developpez.net, where they put a high value on proper formatting, code of conduct, correct spelling (in french).
