What is a Lisp Machine?

Lisp Machines fairly well known in the Lisp world, however, even Lisp seems foreign to most people, including programmers. Lisp machines were common in the 1980s and are still considered one of the most productive developer environments and user experiences. Everything else is still playing catch up which is ironic.

One common phenomenon in the Lisp space recently is Lisp based weblogs. They have been on the rise as one would notice from the aggregation at Planet Lisp. Even my weblog which was intended to be just another blog on the web has a very uneven ratio of Lisp vs other topics.

Glenn Ehrlich is another Lisp blogger. What is very cool about Glenn's postings is that he actually has a Lisp Machine which he purchased recently. He has answered the Lisp machine question rather well here.

He has some really good posts about his user experiences with his LispM.
