Postcards here or separate Tumblr?

So, the postcards thing is going to start happening soon.

When they come in, I’m either going to reblog them here (with a common tag) or put them all into a separate sub-Tumblr.

I can see pluses and minuses to both.

Which do you think would be better? Why?

Notice that this is a slightly different question than “which would you prefer?” because the “Why?” is a really important part of the answer :-)
