@arebelspy, not sure if you want to suggest keeping this thread just about piggybacking, or if general credit questions like this are OK. (If I were king I'd make a separate thread, but I'm not. :) )
Short of draconian moderating, hard to keep people from drifting to a tangential topic from time to time (especially asking the question "what card do I season for TL sales" leading directly to "how will it impact my credit score").
Most the TL questions have been answered and discussed, so short of something shaking up the industry (e.g. the random FTC lawsuits, closure of major companies, etc.), there usually isn't a whole ton to discuss.
I figure the thread will drift back totally on topic soon. :)
(My anecdotal data: credit score is ~815, wife ~805, we have a lot of cards open, maybe 15-20ish, and regularly have 10ish inquiries, usually no less than 7, from the previous 2 years. With a long enough credit history and enough open cards and low utilization, our credit score remains high despite new cards being opened and lots of inquiries. I actually saw our scores go up quite a bit, from the 760 range to the 800 range in the first few years we started travel hacking and accumulating a lot more cards.)
