I totally used that feature, though I feel like its removal got me to use the tags feature of Latest Updates, which is admittedly more useful for me anyway. Now instead of just seeing when some random censored Japanese RPGMaker incest game shows up, I can see if any of the games I actually play got updates or if there's something new to check out.
So, maybe just use that instead, if it suits you? I feel like it's better than a bunch of alert spam, especially if your favorite tag is a relatively common one.
