Let's see.
Back when I started, the map looked like this:

Currently, the map looks like this:

Now, changes.
North-South blobfest in the west: D2 and IRON gone. (Well, Mostly Harmless and Ev0ke are D2 successors.) Deklein is still given out an "outer circle" NC alliance, in this case Goons. Pure Blind and Fade inhabited by smaller alliances, currently well in NC control. (Former Providence alliances there currently.) Goons (and their younger cousin TEST) are in Fountain, fighting against BoB. Fountain/Delve/Querious are still held by BoB (named IT Alliance), after a year of being held by Goons (after a director-level defector disbanded BoB. Goons collapsed when their directors burned out and the CEO ran with the alliance wallet)
Catch-Providence: Huzzah was kicked out by AAA. Catch saw the rise and fall of IAC. AAA became a big boy, before their own burnout problems and collapsed to the Initiative. However, they're taking their former territory back. CVA did collapse to AAA (while it was led by HAVOC), and their space is held by half of Triumvirate (called Northern Coalition alliance) and Ev0ke (ex-D2) and 404 (part of ex-TCF).
Deeper south, ASCN and the rest of the Southern Coalition (against RA) alliances gone, and RA splinters running the place. Russians are still accused of sploits and RMT. Southeast, RA did briefly collapse, but helped by their (former) comrades, bounced back up pretty fast. Russians took over the new lands to the east after a brief stay of other alliances. Vale of the Silent and Geminate are now a buffer between Drone Russians and the NC, mostly controlled by NC.
The major changes in resouce balance have been the introduction of invention, rebalancing the moons (making the northern technetium valuable and the bottleneck instead of the southern dysprosium). Moving high-level plexes into exploration changed balance with the old 10/10s. And then, Dominion changes and upgrading systems made truesec less necessary for a good 0.0 income. The latest change, in specific, has been accused by some to lessen the need for conflict, as it is "more cost effective" to upgrade your own space. Of course, there's always a war going on, but it is not very visible on the official forums. Back when I joined, COAD might be readable at most times, now it's even more just a giant trollfest. First the good stuff moved to the Scrapheap Challenge, but it's pretty bad these days, too. Then there's a forum ran by Kugutsumen (of T20/hacking fame), which is pretty rapidly declining to utter shit, as well.
Also, since the Incursions started for reals. Sinq Laision is still the "most dangerous" region in all EVE.
