You got to love a thread that is titled, How many manual link exchanges can you request within an hour?. It is a shame the thread went off topic into the debate about should you try to send out as many link exchange requests as possible or just go after a very few, but highly relevant exchanges. I would have loved to see the numbers of "manual" link exchanges a single individual can send out within an hour. And even more so the conversion rates on those attempts.
On that note, martinibuster has a good line in msg #23, "The way I see it, it's a balancing act between quality AND quantity because imo the algo judges you against both criteria." But if you can, join the thread and share the numbers on the original topic. That would be nice to see.
