Differences from vBulletin.com?

[harjit]

What are generally speaking the main differences between this forum and vBulletin.com?

For one thing the hacks seem to be here. Are there any other significant differences between the two, in terms of strengths and weaknesses?

I am really busy and want to primarily focus on a single forum, if I can. I find that approach usually seems to work better over the long term when it comes to tech-related forums.

Although in the case of VB there are only two, so I suppose it might be possible to treat both of them as "home".
