Is shared hosting good B? (4.Viewing)

I have recently been offered to invest in a small shared web hosting business (A good friend from the past who has stayed active online while I have not). I am sort of interested, but I can't find much information online. I have been somewhat active for the last year or so, but I have a gap of about 15 years of online inactivity, so I do not have a decent grasp of how things are.

While numbers make sense in his business, my main concern is how growth looks in it. Would anyone be willing to pitch in some numbers?

Thanks!

Don't do it, the big boys eat the little guys alive, web hosts come and go, barely any small hosts survive long term unless they get a buy out.
