[seqfan] OEIS historic sequences

OEIS has some sequences related to itself, for example, A211096 and
A211099, but wouldn't it be nice to add some more? I don't know if the
information can be found, but how about the following sequences, or even if
they are already in OEIS:
- Number of sequences in OEIS on the n-th days of its existence.
- Days after "birth" of OEIS that sequence A(n) was added
- Number of crossrefs of sequence A(n)
(to give an idea if it's much used and maybe interesting (though
interesting is quite arbitrary))
- Flattened: Shortest path from path A(m) to A(n) via crossrefs
(This might need some criterion due to for example "adjacent sequence"
which might be unrelated)
For example, A010000 refs to A070864 which in turn refs to A076566 but
A010000 doesn't so R(10000, 75566) is 2.
Any thoughts or ideas?
