Ideas for article improvement 
Howdy all, the page is looking considerably better than it did not too long ago... good job everyone!  Looking over it, here are a few thoughts I had:
 Any useful content (or simpler phrasing) in the Fibre Channel 8B/10B encoding article should be merged in and that article set to redirect here
 The "How it works" section should probably be moved down below the "Technologies that use 8b/10b" so that the encoding tables can be made to be a subsection of "how it works".
 While the concept described in the sentence about the Ethernet transformer is correct, the overall statement looks technically wrong since 1000Base-T doesn't use 8b/10b.
 Lastly, it seems like the intro could be re-written to be somewhat easier for laymen to understand.
Anyone interested, please feel free to be bold and do any (or all) of these!  — T-C
