If anyone is curious what's going on at SI, it seems as though they've started publishing monthly progress reports on their blog. The latest was published less than a week ago for the month of February:
Thought it might be a good idea to take a minute to positively reinforce the people at SI for their work. Here on Less Wrong, it seems as though we spend a fair amount of time criticizing what they're working on, which is of course valuable. But on the whole, I think there is a very good case they're doing very important and beneficial work. So, go SI!
You might be technically right, but "research" does suggest going in the direction of original research, so it's better to clarify by saying "we reviewed literature on X" or something like that instead of "we researched X". Also, agreed with shminux about triggering loud crackpot alarm with "we researched Riemann hypothesis", it might even be a good idea to go back and edit this out of the report.
In particular I'd say "did unpublished research on topic X" sounds like "did research that might be published (i.e. is valuable and original)" whereas "researched topic X" sounds more like "read about things."
