Firstbits, while being a clever idea, produces a less desirable solution in comparison to the current alias proposals. In addition to Matt's reasons, I would like to add that it is still a block of random characters, just shorter. It creates the undesirable effect of having addresses short enough that people may try to type it in rather than pasting or scanning, which is more error prone. One obvious scenario for potential exploitation would be if a large organization adopted a firstbits address for donations. Others could immediately try to collect similar addresses in hopes of a typo. A second would be if the organization published the firstbits address on a poster in a public location. Someone could easily secure a firstbits address which was one character longer, then stencil that extra character on to the poster.
