Galaxy and external browser alike make changes to user interfaces over time, but the basic concepts and methods of this particular tutorial are still valid. Small differences in results were expected even in the short term - some of the inputs are updated nightly (for example, all tracks sourced from Genbank, obtained through UCSC and many other sources, are - including RefSeq), others at regular intervals (such as dbSNP). These differences are not important for the overall tutorial goals.
The results are just a simple comparison answering the original question "The list of coding exon having the highest number of single nucleotide polymorphisms on chromosome 22". It is not particularly relevant from a scientific perspective. The goals of the tutorial are to aid new users in becoming familiar with the user interface and basic functionality: data importing, interval comparisons, simple manipulations, workflow creation and re-use, plus history sharing.
When you are ready to move on, there are additional tutorials available to explore on the public Main Galaxy server itself and others donated by the community in our wiki that in most cases can be executed on Main.
As you advance, the 'Resource' on the Teaching hub can be explored for more in-depth guided analysis examples. Keep in mind that these are designed to be often run in a cloud Galaxy environment (may utilize tools not included on the Main instance) and are formatted as workshop resources. However, they are still a great option if you are unable to attend a live hosted tutorial Event (http://wiki.galaxyproject.org/Events)l, or just wish to prepare early before attending one. "Teach" will be filling out more in the near term as the newly formed Galaxy Training Network (http://wiki.galaxyproject.org/Teach/GTN) works towards its current goals.
Hopefully this helps with the first step, our 101, and with future learning, Jen, Galaxy team
