Adobe / Macromedia
Well, this is some kind of news. I'm at a loss to see how anyone but possibly some shareholders will benefit though? This is not a sector that really needs consolidation, and (assuming product lines merge) I think most designers and developers will miss the Macromedia alternative.
Does it matter who makes Flash? Dunno. Dreamweaver vs. GoLive? I'd take DW, but I'm not going to pitch my tent outside Adobe's offices to petition for its continued development. Homesite? I'm still using Allaire's version. And the silver lining - I guess I can take Fireworks off my must-learn-more-about list.
