I've never used Kagi (only heard of it in this thread) and I'm writing to say, "I believe you." Business models are hard. I can also understand the feelings of the disgruntled; it always sucks to feel like something has been 'taken away'.

Thanks for making paid search for the masses (with funtioning filters, apparently) a reality. By the testimony of many here, your results aren't bad. I'll be giving Kagi a try.
