As you might have read from Jim or Atanas, Embarcadero has a new blogging platform at https://blogs.embarcadero.com .
This is going to replace the use of a section of the Idera community, at https://community.idera.com/developer-tools/b/blog. All content from the developer tools section of the Idera community is being migrated (at least, this is the plan).
I'll use it the new blogging platform (my posts are filtered at https://blogs.embarcadero.com/author/marcocantuembarcadero-com/), along with my historical blog site, https://blog.marcocantu.com/.
As for forums and general programming questions, there was a decision to rely and leverage external communities, and we listed a number at https://blogs.embarcadero.com/community/. For English-speaking people I can recommend Delphi Praxis https://en.delphipraxis.net/ and StackOverflow https://stackoverflow.com/questions/tagged/delphi.
