Has this ever happened to you?

I hate it when the labels on the x-axis overlap, but this can be hard to avoid. I can stretch the figure out, but then the data become farther apart and the space where I want to put the figure (either in a talk or a paper) may not accommodate that. I've never liked turning the labels diagonally, so recently I've started using coord_flip() to switch the x- and y-axes:
ggplot(chickwts, aes(feed, weight)) + stat_summary(fun.data=mean_se, geom="pointrange") + coord_flip()

It took a little getting used to, but I think this works well. It's especially good for factor analyses (where you have many labeled items):
library(psych)
pc <- principal(Harman74.cor$cov, 4, rotate="varimax")
loadings <- as.data.frame(pc$loadings[, 1:ncol(pc$loadings)])
loadings$Test <- rownames(loadings)
ggplot(loadings, aes(Test, RC1)) + geom_bar() + coord_flip() + theme_bw(base_size=10)
It also works well if you want to plot parameter estimates from a regression model (where the parameter names can get long):
library(lme4)
m <- lmer(weight ~ Time * Diet + (Time | Chick), data=ChickWeight, REML=F)
coefs <- as.data.frame(coef(summary(m)))
colnames(coefs) <- c("Estimate", "SE", "tval")
coefs$Label <- rownames(coefs)

ggplot(coefs, aes(Label, Estimate)) + geom_pointrange(aes(ymin = Estimate - SE, ymax = Estimate + SE)) + geom_hline(yintercept=0) + coord_flip() + theme_bw(base_size=10)
