These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Lisa Foiles is really the only cast member during the Dork Age that is remembered. Mostly because she has made a name for herself in the nerd community.
It's Popular, Now It Sucks: The last 4 seasons of the show had wildly higher ratings than the previous 6 seasons (the late 90s still saw many households without cable; Y2K somehow made subscriptions, & thus Nick's viewership, increase dramatically), yet those who saw the entire run of the program by & large insist the first years were the best. Mostly Justified in that most of the writing staff & all of the actors (including the final remaining original cast member, Josh Server) left that year. The new guys might've just not been up to snuff.
Retroactive Recognition: You won't believe how many video website comments are centered on people realizing that comedian Gabriel Iglesias was once a cast member on the show (though, much like Gilbert Gottfried, Eddie Murphy, and Gail Matthius on season six of Saturday Night Live or Joan Cusack and Robert Downey, Jr. on season 11, Gabriel Iglesias was a cast member on a season that was considered Seasonal Rot).
As mentioned in the trivia page, Lisa Foiles has her own web series and is featured in a few others.
Danny Tamberelli was already famous when he started in All That thanks to his antics as little Pete on The Adventures of Pete & Pete. He may have abandoned the comedy scene during his college years and became focused mostly on music (he has his own band), but during the last few years he has been writing comedy sketches around for his comedy troupe herenote and even former All That cast memebers such as Server, Saul, Thompson and Foiles have participated with him as guests, and now he is also being involved in voice acting with Jimmy DeSanta in Grand Theft Auto V and other few projects around.
Josh Server appeared as some cameos in other Dan Schneider series, such as Drake & Josh. He is also doing comedy in the internet.
Jamie Lynn Spears may be redundant if you remember whom she is sister from and she also had this little show named Zoey101, meanwhile All That was finishing its final season production.
To many, it would come as a surprise that Mark Saul was once also part of the show cast during the last two seasons of the original run (he even wrote some sketches with Tamberelli aboard). After that, he had some roles in Grey's Anatomy and in The Social Network. He also has a comedy website.
Jack DeSena from the relaunch era, has a familiar voice for some people... that is because he went to do Sokka's voice in Avatar: The Last Airbender, around the same time.
The most damning example of all is Kenan Thompson, who went from being on a kiddie version of Saturday Night Live (this show) to being on the real deal in 2003 (meaning Kenan's been on SNL for 10 years, almost as long as Tim Meadows, the first black SNL cast member to stay on the show for more than five yearsnote To compare: Garrett Morris from the first five years was on the show until 1980, Yvonne Hudson was barely on the show for a year, Eddie Murphy was on the show from 1980 to 1984, Damon Wayans was fired in 1986 due to creative differences with Lorne Michaels, Danitra Vance left in 1986 because she hated being put in stereotypical roles, Chris Rock left for the same reason Danitra Vance did after three years, Ellen Cleghorne left after four years, Jerry Minor was on the show from from 2000 to 2001, Dean Edwards left the show in 2003 due to creative differences, and Finesse Mitchell — the Mitchell who replaced Kel — was let go after three years because NBC didn't have enough money in their budget for excess cast members. Maya Rudolph, Kenan Thompson, Tracy Morgan, and Tim Meadows are the only black SNL cast members who stayed on the show for more than five years — Tracy left after seven years, Maya left after nine, Tim Meadows left after ten, and Kenan Thompson is still on the show, and if he stays on, he will break Tim Meadows' record for longest-staying black cast member. The only other black male cast member in the 2012-2013 cast is Jay Pharoah, who's been on the show for three years' now and no one knows whether or not he'll stay for long, though he might, given that he's won the audience over with his dead-on celebrity impressions and is now cast as Barack Obama, a role once held — with much controversy — by Fred Armisen, and Lorne probably does not want to let Pharoah go like he had to do with Will Ferrell when he played George W. Bush). Sadly, his comedy partner and friend, Kel Mitchell, didn't make the cut. That aside, it's still good that someone from All That found fame on another sketch show — one that's been around for a long time, also has a boatload of memorable characters and sketches, and, for better or worse, is still alive in the public consciousness.
Seasonal Rot: The seasons during the 2000s, known as the "Relaunch Era" (seasons 7-10), at least for the fans of the 'Golden Era'.
