FIN tag - overcrowded ?

Hi

I have added my user to tag FIN, now I've got messages on

1. - SAP HANA
2. - SAP FI
3. - SAP CO
4. - coming conferences or events
5. - VIM software
6. - IoT

There is too much information and some might not be directly in use for FI.

640 elements - 636 blogs and 4 questions. In the case of blogs I get confused on what is:

1. news from SAP
2. technical documents prepared by users
3. blogs (experiences) prepared by users

How can I distinguish between them ?

Kind Regards
