Why not? The internet is timeless. That is one of it's beauties. Discussions can continue across geography and time.
FWIW, bumping a thread like this is fine, as the topic itself is still relevant.
It's a problem (and we may delete the bumping post) when the majority of the old information in the thread is not relevant.
Examples:
- There's a thread from 2005 or something, about how to use the same Windows image for Bootcamp and Parallels, and people saying that one cannot do this. Bumping it today and saying, "Hay guys, just do xxx" would be in bad taste, because obviously almost
everything related to this situation has changed since 2005. Or bumping a thread asking about running Windows apps on a Mac that was written in 2003 to say that you recommend using Bootcamp.

Just start a new thread.
- Bumping an ancient thread to render a not particularly sophisticated opinion (e.g. one's whole post is "LOL me too") would also be frowned upon.
- If next year, Apple releases a totally new keyboard interface in iPhone firmware 3.0, you probably shouldn't bump this thread again and say, "Hay guyz, OMG, how come u guyz only type 40WPM? I type 80 WPM ROFL" ... this would brand you as a n00b.
This however is fine.
OTOH... now that there's an App Store, how are people
measuring their typing speed? Which app do you all use? Using Idle Hands (free), I come out about 20-30WPM including letting auto-correct do its job (as well as having to go back and fix when it doesn't). My reference computer keyboard speed is around 75-85 WPM....
