1) Yes, the plan is to add more blogs, books, ... so tell me where to put them. Due to limited space, they better be acronyms though

2) The map is not a race. The map is not meant as a test to pass for a certificate or an achievement award either. It's not like "First you must get under 30k spending to pass level 4". The spending level is meant to be representative for the blogs. We are of course really looking at spending efficiency like this: http://forum.earlyretirementextreme.com ... 322#p99322 ... but that concept is hard to convey in a table with 3-5 words per field. The point is to gauge what people spend on something that on the outside looks like a more or less normal lifestyle, e.g. not under a bridge, not in a mansion.
3) People are not meant to conform to a single level. However, I have noticed that in reality, fields at the same levels OFTEN go together. One might say I arranged them according to my anecdotal biases. But it's not like you find your savings rate or your spending and then go read off your level. That would be totally misunderstanding the point. A full time worker in the food service industry living paycheck to paycheck together with 4 other room mates and barely making ends meat isn't automatically level 5 because they only make 20k/year. They're clearly level 1. Similarly, a doctor with a 200k salary isn't automatically level 5 because they put away 100k. They could be level 1.
4) Levels more than two degrees off aren't meant to be theoretically "incomprehensible" as much as they simply aren't practically considered relevant to onself. Compare goals at level 4 and 6. Lots of heated discussions between "4% because internet" and "3% because history". Less heated between the latter and "4% because Trinity". Or compare levels 4 and 5. Both have 4% SWR but they have them for different reasons.
On the "travel channel", higher levels might be dreams but they are seen as impractical ("what sell my house and car and just move to some other country? I don't think I could") vs ("why would I go backpacking when it's more interesting to go and live among the locals for an extended period?")
5) I also considered putting in savings and networth but then quickly ran into the problem of comparing people who just started vs people who had been saving for a few years. E.g. it would be nice to have a column with FU Money, 10x years of savings, ... 25x, 100x, ... but mostly that just measures how long someone has been saving.
