D20 Future/Modern Skill Synergies

[Xath]

There are quite a few skills in D20 Future/Modern which don't transfer over to the D&D synergy table. I realize that the book says that it's up to the DM's discression, but if Knowledges have synergies in D&D, shouldn't they have them in Modern or Future?

What kind of synergies do you offer in your D20 games?

The Knowledge skill synergies were added in 3.5, which came out after d20 Modern. Hence the lack of knowledge synergies in Modern.
