squints

Hi,

I am a new webmaster experimenting with various methods across a few of my developing sites.

I have an adult PR2 & PR3 as well as a mainstream PR4.

Regarding my two adult sites, they're both fairly new but the traffic to them is growing each day. I'd ideally like to sell textlinks on these two sites for 180/365 day periods.

Few questions:
1. Does PR still matter?
2. Does anyone continue to sell links?
3. How much value does a PR2/PR3 really possess?
4. Would you suggest trading links, and essentially using placeholders, until I can sell all my spots?

Any advice/suggestions would be greatly appreciated!

Thanks guys
