For those curious about joining Alacritysim, I have compiled a fair review here of both the good and bad, as well as some images. There are two reviews, one in 2011 and one updated now for 2015.
It's recommended that you read both if you want to know what the culture is like and see what the site trend is. This is especially for anyone who might be looking to invest real money in playing. It gives you an idea of how Alacrity is doing over the years.

Review 2015: http://www.virtualpetlist.com/threads/alacritysim-introduction-and-information-v2.27221/
A lot has changed on the site, so don't be afraid to see if this is right for you. Because it's definitely a niche site.

The short version that I can compile is:
YES if you enjoy breeding sims
YES if you like traditional artwork and decorating
YES if you like dogs
CAUTION if you are looking to spend real money.
CAUTION if concerned about customer care.
NO if you are a more social player looking to interact, or find interacting platforms important.
NO if you are not looking to spend real money. It is mostly pay to win. It is possible to succeed without but difficult as you will need game credits to do well. Trading for game credits and virtual cash is allowed.
