Reiserfs is a completely new file system initially designed by Hans Reiser
and his team that has journalling capabilities, uses balanced b-trees for directory
searches (unlike ext2 which uses linear dsearch) and block allocation, 
features highly optimized file access. Go to http://www.devlinux.com/namesys
for more info
 
ext3 adds journalling to the ext2

XFS(tm) is an SGI project (open source) to port their high performance, fool
proof, journalling, 64-bit file system to Linux. For details see 
http://oss.sgi.com/projects/xfs/

Well, you can say so in two words :))

Yes, ext2 has had support for ACLs in its design, but they are implemented
by off mainstream patches (sorry, no URLs :()

Patches for ext2 support for capabilities on the 2.3 kernels can be found in
the Linux kernel archive
(ftp://ftp.kernel.org/pub/linux/libs/security/linux-privs/kernel-2.3/)

Well, minimal fscking is always necessary, but the journalling feature makes
it really unnoticable.
