Note, the master will be the one which shows up in the questions, even if they are tagged with one of the synonyms.
I "voted" for
adf in a comment to Bart, but I'm suggesting
ambient-data-framework as the master tag.
In addition to everyone's points on SEO and how acronyms can confuse new users, also consider that acronyms can:
- Change. Did you notice the 2013 docs using
CME? What about
- Conflict. For example, SDL Campaign Manager is another SDL product. If we have integration questions here, should it be tagged
- Be Seen Out-of-Context. As an example, companies (like mine) may ask their staff to add signatures to emails and footers to documents, even for short responses to colleagues. You never know when and where something will be read.
A proper tag can help give Stack Exchange questions context if seen via RSS, email, on other sites, or even years later.
