I'm a total newb (started with Linux a week ago) and I went with Mandrake initially. After some searching around I found the Slackware community to be extremely helpful and resourceful thus made the switch. That and the fact that everyone says Slack is the best out there made me want to give it a try.
I succeeded in installing it on an old PIII 500 with 128MB RAM and 32MB Video and it was fun stuffing it up a couple of times only to learn how to install it very well now.
As others before me have welcomed me, I welcome you to the Slackmunnity.
