I've seen them all..been to every one of them at least once.
I was doing keyword searches with Veronica and Gopher, I have used Mosaic and Pipeline, and searched Compuserve with a 2400 BAUD modem at $5.50 an hour.
IOW, I've been doing this a long time.
You have very little to offer in the way of advice.
Stick around to FR for a while and you'll be exposed to a wealth of other sources.
