The early days...... Dreamweaver...... confusion!

sIFR

sIFR at work on Jason Santa Maria’s site jasonsantamaria.com

sIFR

The best of both worlds: the accessibility and ‘selectability’ of HTML but with (some of)* the benefits of Flash-based rendering.

* = Layout is still determined by HTML

It’s brilliant, but essentially it’s a hack; not a solution.

While sIFR gives us better typography today, it is clearly not the solution for the next 20 years.

It is but a nice stopgap for people who value the importance of typography and don’t want to wait 1, 5, or 10 years for browser makers, OS vendors, and type foundries to figure out a better solution.

The moment that happens however, sIFR will lift right out and give way to whatever other method is available.

Protection is needed for font foundries to counteract font piracy (as with EOT).

More fonts need to be made available so that the choice can improve. In its current state, the limited choice is turning into not much more than an alternative list of web-safe fonts.
