Activity stream - extending Rails app data model / database

[Paweł Paprota]

Hi all,

So I have done some more thinking with the activity stream and came up
with two options for general approach to the implementation:

What do you think about those options? Maybe you see some other ones?
Personally I like the flexibility of extending the data model, it also
decouples activities from the actual data but I don't have enough
context (like database server load etc.) to judge whether this is
acceptable.
