I thought this was a good idea when it was first suggested. I still 
think so.

Some time ago, I made a suggestion for improving the OEIS graphs. ...

My suggestion to improve this situation is as follows: For large-valued
sequences, instead of plotting
log(a(n)+1) or log(|a(n)|+1), plot

     qlog(n) = arcsinh(a(n)/2)/(ln 10)

(qlog stands for quasilog). You can think of qlog as a sign-preserving
log.
